RadaR LeveL SenSoR U N on-ContactMeasurement U C ontinuous LevelMeasurement U P ulse RadarMeasurement Range: 0.254 to 15 m (10" to 50')U S imple PushbuttonCalibration U C ommunicationsStandard The LVRD500 Series a logical extension to the ultrasonic sensor series, is designed for applications requiring non-contact liquid level measurement, in which ultrasonic level measurement is not acceptable.The LVRD500 Series radar technology can be adjusted for variables such as materials to be measured, vessel configuration, and system interface. These sensors are ideal when vapor, dust, or a foaming surface prevents ultrasonic-wave measurements.LVRD500 Series radar sensors can detect the level under a layer of light dust or airy foam, but if the dust particle size increases, or if the foam or dust gets thick, they will no longer detect the liquid level. Instead, the level of the dust or foam will be measured. Internal piping, deposits on the antenna, multiple reflections, or reflections from the wall can interfere with the proper operation of the radar sensor. Other sources of interference are rat-holing and bridging of solids, as well as angled process material surfaces that can reflect the radar beam away from the receiver.The sensors use improved micro-wave-pulse technology to track any target material from the tip of the antenna to the bottom of the tank. Their power, pulse widths, and sensitivity depend on the distance of the target from the antenna and the dielectric constant of the reflecting material.LVRD500 sensors feature “echo marker” signal process-ing, making them among the most technologically advanced pulse radar systems on the market. This technology provides reliable, continuous pulse shapes unaffected by environmental factors such as temperature, vacuums, methane, steam, pressure, carbon dioxide, vapors, and condensation.The antenna comes in polypropylene or an optional high resistance PTFE that can help protect against material buildup. Simple mounting and push-button calibration make for easy installation. The sensor can be threaded directly into a 2 NPT metal or plastic flange. The tank must havea metal bottom to stop the microwave signal.LVRD501 SeriesLVRD501-RS232 shown smallerthan actual size.KFor high temperature PTFE, add suffix“-HT” to model number, for additional cost.For PTFE antenna, add suffix “-PTFE” to model number, for additional cost.For 316 SS housing, add suffix “-316SS” to model number , for additional cost.For 2" Tri-Grip sanitary mount and PTFE antenna add suffix “-S” to model number, for additional cost (only available on LVRD 501 series).

OverviewThe intelligent non-contact liquid level sensor (hereinafter referred to as the liquid level sensor) adopts advanced signal processing technology and high-speed signal processing chip, which breaks through the influence of container wall thickness and realizes a true non-contact type of liquid level height in a closed container Detection. The liquid level sensor (probe) is installed on the upper and lower sides of the outer wall of the container to be measured (the high and low levels of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect production. It can detect the liquid level of various liquid toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers. The liquid level sensor has no special requirements for the material of the liquid medium and non-metallic container, and can be widely used. XKC-Y25-XXX series products are specially developed for non-metallic container liquid level detection. This series of liquid level sensors are divided into four signal output control methods, namely high and low level output interface, NPN output interface, PNP output interface, RS485 Output interface; the four signal output modes correspond to the following four models:Serial number type number signal interface1 XKC-Y25-V High and low level output interface2 XKC-Y25-NPN NPN output interface3 XKC-Y25-PNP PNP output interface4 XKC-Y25-RS485 RS485 output interface2nd.Product Features1. XKC-Y25-XXX non-contact liquid level sensor is suitable for non-metallic containers. The product detects the liquid through the detection signal through the non-metallic container and the outer wall of the pipeline, without direct contact with the liquid, and will not be subject to strong acid, Corrosion damage caused by corrosive liquids such as strong alkalis is not affected by scale or other debris, and it can be completed to detect whether there is liquid inside the container or pipeline.2. It can support high and low level output, NPN, PNP signal output (please refer to the manufacturer's instructions when selecting the model).3. The detection liquid level is accurate and stable, and cold, hot and boiling liquids can be detected.4. Pure electronic circuit structure, non-mechanical working mode, stable performance and long lasting service life.5. High stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5-24V power adapters on the market.6. It has a wide range of application and strong sensing capability. It can penetrate and detect the liquid level in various non-metallic containers, such as plastic, glass, ceramics and other containers. The sensing distance (container wall thickness) can reach 20mm; liquid, powder, Particles can be detected.7. Open collector output mode, wide voltage range (5-24V), suitable for connecting various circuits and product applications.3rd.Product ApplicationsThe intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect the presence of liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the presence of distributed capacitance on the sensor. When the liquid level is slow When the sensor is slowly raised, the parasitic capacitance of the liquid will be coupled to the static capacitance of the sensor, making the capacitance value of thesensor larger. The changed capacitance signal is then input to the control IC for signal conversion, and the changed capacitance is converted into a circuit signal The MCU calculates and judges the degree of the change in the analog quantity. When the change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point. 4th.Product parameterProject name ParametersProduct model XKC-Y25-VSupply voltage（Vin）（DC 5V-24V）Output mode High and low levelPower ripple requirements ≤200 mVelectric current ≤5mAResponse time 500mSWorking temperature -20~105℃humidity5%~100%Induction thickness(Sensitivity) range≤20mm（Container wall thickness)Liquid level accuracy±1.5mmLine length 500MM（±10MM）(Bulk can be customized)Terminal sequence Brown (power supply positive), yellow (signal output) Blue (power negative), black (COM terminal)Material PC V0 Fireproof materialWaterproofperformanceIP67Safety standardcertificationCEEnvironmentalprotection certificationROHS-2.05th.product selectionHigh and low level————Model: XKC-Y25-V （DC 5V-24V）6th. Clearance requirementsRequirements for the clearance between the contact surface of the sensor (or probe) and the outer wall of the container The contact surface of the sensor (or probe) and the outer wall of the container should be tightly pasted with AB or other solid-resistant glue. If there are special requirements, the gap should be less than 0.5mm, preferably no gap, otherwise it may affect the measurement accuracy.7th. Installation methodThe following is the installation method of XKC-Y25 series products, the installation method of other models is the same.(1) Requirements and installation methods of the tested container The tested containers are divided into 3 categories according to their materials:The first category: insulating material containerContainers made of non-metallic materials with flat surface, uniform thickness, compact materials, and good insulation properties; such as glass, plastic, non-absorbent ceramics, acrylic, rubber and other aterials or their composite materials.installation method:1. If the container wall where the measuring probe is installed is of multi-layer material, the layers should be in close contact with each other without bubbles or gas interlayers. The inner and outer surfaces of the container wall should be flat.2. Wall thickness: 0-20mm3. Tank type: spherical tank, horizontal tank, vertical tank, etc.4. The installation method of this kind of material container is shown in Figure 1;The probe can be pasted and fixed with glue or fixed on the outer wall of the container with a non-metal bracket.Try to avoid metal and other parts where the probe is installed, so as not to affect the detection.The position where the probe is installed should try to avoid the position where the liquid flows.There should be no silt or other debris inside the container facing the low-level probe, so as not to affect the detection;Figure 1-1 The top image of a non-metallic container of a probe installation diagramFigure 1-2 The above diagram of the installation of two probes in a non-metallic containerThe second category: metal conductive material containerContainers made of metal or other conductive materials; such as stainless steel, copper, aluminum alloy or materials with electroplated metal layers on the surface. Because capacitive sensors are sensitive to all conductive objects, this type of container cannot be directly attached to the outer wall of the container; therefore, for containers of this type of material, holes need to be made on the side of the container. The installation method is as follows.installation method1. Prepare two rubber plugs and the necessary tools for opening threaded holes;2. Two threaded holes are opened in the high position and the low position respectively, and the hole diameter matches the size of the rubber plug;3. Put a rubber plug on the threaded hole and tighten it to check for water leakage, and add glue to seal if necessary;4. Paste the sensor on the rubber plug with glue and fix it with the bracket. After the glue has solidified, remove the bracket. The installation of the metal container is shown in Figure 2.Figure 2-1 Installation diagram of a sensor in a metal containerFigure 2-2 Schematic diagram of installation of 2 sensors in a metal containerThe third category: non-metallic materials that absorb waterContainers made of ceramics, tiles, bricks, tiles, cement, wood boards and other materials are insulators or weakly conductive. This kind of container may not be detected when it is close to the liquid level sensor when it is dry and without water, but when the container is filled with water, the container wall will absorb water, causing the container wall to become a conductor; even if the container is empty When the sensor is close to the container wall, the signal will also be detected.If the sensor is to be used on a container of this type of material, the installation method should be in accordance with the installation method of a metal container. For the installation method, see "Class 2: Metal Conductive Material Container" and Figure 2; or use an external pipe to install. External pipes are divided into external non-metallic pipes and external metal pipesThe installation method of external non-metallic pipes is shown in Figure 3-1 and Figure 3-2. The installation method of external metal pipes is shown in Figure 4-1 and Figure 4-2..Figure 3-1 Schematic diagram of the installation of a sensor in an external non-metallic pipeFigure 3-2 Schematic diagram of the installation of two sensors on external non-metallic pipesFigure 4-1 Schematic diagram of the installation of 1 sensor in an external metal pipeFigure 4-2 Schematic diagram of installation of two sensors on external metal pipesFigure 5 The sensor is installed on the iron pipe with the three-prong joint (the installation diagram of metal andwater-absorbing container)The sensor is installed on a non-metallic water pipe with a smaller diameter8th.Application environment1. XKC-Y25-V, XKC-Y25-NPN/PNP (5-12V)It is only applicable under the conditions of good EMC environment. For example, the connection with MCU, and some simpler load applications, such as LED indicator lights, piezoelectric buzzer, etc. And there is no high-power capacitive and inductive load and harsh electromagnetic environment on the power bus.2. XKC-Y25-NPN/PNP (24V), Y25-RS485 (24V)This model is carefully designed for harsh industrial environments. Added professional EMC components, such as spike absorption, electromagnetic compatibility, and transient suppression and surge protection. It can be directly connected to PLC, electromagnetic relay, etc. It has a very strong anti-interference ability and is suitable for all harsh industrial application environments.9th. output principle and recommended wiring methodHigh and low level output drive small electric relay (coil current ≤100mA) Product Applications:1.When the black line is suspended, it is positive output:When liquid is sensed, the transistor cuts off and outputs a high level, and the relay does not pull in when it is powered off;When no liquid is sensed, the transistor turns on and outputs a low level, and the relay is energized and closed.2.When the black wire is grounded (connected to the negative pole of the power supply 0V), it is a reverse output: When liquid is sensed, the transistor turns on and outputs a low level, and the relay is energized and closed;When no liquid is sensed, the transistor cuts off and outputs a high level, and the relay does not pull in when it is powered off.10th. Sensitivity adjustmentIf the liquid level cannot be detected or the distance between the detected liquid level and the Y25 sensor is deviated, Open the back cover of the sensor and use a small screwdriver to adjust the sensitivity knob.There are two setting methods:1. Turn counterclockwise to increase sensitivity.2. Turn clockwise to lower the sensitivity.11th. Product size and physical map12th.Other matters needing attention(1) The viscosity of the measured liquid mediumWhen the dynamic viscosity is less than 10mPaS, it is measured normally. 10mPaS<dynamic viscosity<30mPaS may affect the detection. When the dynamic viscosity is greater than 30mPaS, it cannot be measured because a large amount of liquid adheres to the container wall.(2) Note: As the temperature increases, the viscosity decreases, and most high-viscosity liquids are more affected by temperature. Therefore, pay attention to the influence of liquid temperature when measuring viscous liquids.(3) Pay attention to keeping the level gauge clean, try to prevent corrosion and avoid violent collisions and blows from other objects.(4) During outdoor installation, avoid direct sunlight and rainwater directly flowing to the main body of the level gauge, and keep away from high heat sources and pay attention to ventilation. If the ambient temperature exceeds the rated temperature, corresponding cooling protection measures should be taken.(5) When the ambient temperature is lower than the normal operating temperature range of the level gauge, an instrument protection box or other protective rain cap devices can be used for antifreeze protection, and pay attention to keeping the level gauge dry. The sensor should be regularly maintained and inspected.
