The SERIES TDFS on change of flow.to cool. The flow Higher FlowEnsure that the process fluid is compatible with the wetted materials, and do not exceed the maximum device ratings.Ensure that the system is not pressurized before installing or removing this device or other objects from the system. The deviceand/or object may become a projectile.Do not use with abrasive fluid mixtures (The polysulfone may be abraded.)Use caution if fluid temperature changes or fluid composition changes are present in the end application. Verify that the deviceoperates properly if either is present. The setpoint will shift if the specific heat, density or viscosity of the fluid changes.Mount the TDFS so that the sensor extends into the flow by 10-25% of the pipe ID. Use PTFE tape on the process connection to reduce the risk of leaks. For proper flow measurement, the sensor must be fully submerged in the fluid. Bubbles, turbulence, and sediments will cause improper operation. For best operation, mount 30° to 150° off vertical on horizontal runs (See Figure 2). Allow a straight run of at least 12 pipe di-ameters upstream and 5 pipe diameters downstream to ensure optimal flow measure-ment. For optimal repeatability, ensure the flow switch is not operating in the transition region (laminar to turbulent flow).ELECTRICAL CONNECTIONThe power input and switched outputs are individually fused at 0.5A and are reverse polarity protected. A shielded 4 conductor cable provides the electrical connection to the TDFS. The cable drain wire must be connected to earth ground in CE applications or when strong RF fields are present.Two open collector switched outputs are provided. One is normally open (NO), and the other output is normally closed (NC). The output logic is shown in Table 1.SETPOINT ADJUSTMENTThe setpoint may be adjusted with the supplied magnet. There are two setpoint targets on the unit located under the LED status indicator on opposite sides of the unit (see Figure 4). Either setpoint target may be used, and either end of the magnet may be used. If the setpoint does not set easily, try reversing the magnet.Steps:1) Ensure that the unit is properly installed and powered.2) Set the system flow to the desired setpoint flow rate.3) Tap the setpoint target three times with the supplied magnet. Move the magnet approximately 2 inches away from the target between each tap. The taps should be approximately 1 second apart. The LED status indicator will blink slowly when the setpoint request is recognized. The slow blink will stop when the setpoint has been stored.©Copyright 2017 Dwyer Instruments, Inc.Printed in U.S.A. 5/17FR# 443813-00 Rev. 4STATUS INDICATORThe status indicator (See Figure 4) provides visual indication of the TDFS status. Two status indicators are located on opposite sides of the unit. Each status indicator has one red LED and one green LED. Table 2 describes the status indicator states.If an error condition is present, the unit will continue measurement attempts until the problem has cleared. The status indicator will cycle on and off during this time.AGENCY APPROVALS AND TEST STANDARDS CE: CENELEC EN 55011: 2006 CENELEC EN 61326-1: 2006 IEC 61000-4-2: 2008 IEC 61000-4-3: 2006 IEC 61000-4-4: 2004 IEC 61000-4-5: 2005 IEC 61000-4-6: 2006 CENELEC EN 55022: 2006 FCC PART 15 CFR TITLE 47: 2008 ICES-003: 2004 Digital Apparatus (Industry Canada) ANSI C63.4-2003 2004/108/EC EMC DIRECTIVEMAINTENANCE/REPAIRUpon final installation of the Series TDFS, no routine maintenance is required.

The parameters are variable and can be changed by two means: Set by the customer using PC-Tool software or the handheld ZTH US.For fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. A feedback signal is provided for position indication.The LF24-MFT-S-20 US actuator provides 95° of rotation and is provided with a graduatedposition indicator showing 0° to 95°. The actuator will synchronize the 0° mechanical stop or the damper or valves mechanical stop and use this point for its zero position during normal control operations.The actuator uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuator’s exact position. The ASIC monitors and controls the brushless DC motor’s rotation and provides a Digital Rotation Sensing (DRS) function to prevent damage to the actuator in a stall condition. The position feedback signal is generated with out the need for mechanical feedbackpotentiometers using DRS. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. The LF24-MFT-S-20 US is mounted directly to control shafts up to 3/4” diameter (K6-1 clamp) and anti-rotation bracket. A crank arm and several mounting brackets are available for damper applications where the actuator cannot be direct coupled to the damper shaft. The spring return system provides minimum specified torque to the application during a power interruption. The LF24-MFT-S-20 US actuator is shipped in the zero position, compression against seats or gaskets for tight shut-off is accomplished manually.Spring return control damper actuators shall be direct coupled type which require no crank arm and linkage and be capable of direct mounting to a shaft up to a 3/4" diameter and center on a 1/2" shaft (default). Actuator shall deliver a minimum output torque of 35 in-lbs. The actuator must provide modulating damper control in response to a 6 to 9 VDC control input from anelectronic controller or positioner. The actuators must be designed so that they may be used for either clockwise or counter clockwise fail-safe operation. Actuators shall use a brushless DC motor controlled by a microprocessor and be protected from overload at all angles of rotation. Run time shall be constant, and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position feedback. Actuators with auxiliary switches must be constructed to meet the requirements for Double Insulation so an electrical ground is not required to meet agency listings. Actuators shall be cULus listed and have a 5 year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.Factory settings Default parameters for 6 to 9 VDC applications of the LF24-MFT-20 US actuator are assignedduring manufacturing.

火电厂用20号钢珠光体球化评级标准前言本标准是根据原电力工业部1995年电力行业标准计划项目(技综［1995］44号文)的安排制订的。

制订本标准的目的，是为了保证火力发电厂金属技术监督范围内的各种碳钢部件的运行安全。

碳素钢系列在电力工业中有着广泛的应用，而该系列中的20号钢，更是电站锅炉许多重要部件的主要用材。

按GB 3087标准供货的20号钢无缝钢管用于制造低、中压锅炉管件，按GB 5310标准供货的20G无缝钢管用于制造高压和更高蒸汽参数的锅炉管件。

一般来说，20号钢主要用于壁温不超过450℃的锅炉受热面管、蒸汽管道和集箱。

国外锅炉管件材料中，与按GB 5310标准供货的20G钢管相类似的主要有德国的St45.8/Ⅲ和日本的STB42钢管。

美国用SA 106B作锅炉联箱和管道，用SA 210A-1作水冷壁、过热器及再热器管。

20号钢在高温长期使用过程中，其组织中的珠光体会发生球化现象，即珠光体中的渗碳体(碳化物)形态由最初的层片状逐渐转变成球状，材料的力学性能也随之下降。

球化现象的产生是因为层片状渗碳体的表面能较高，它总是要向能量低的球状渗碳体形状转变。

在常温下，由于原子的扩散速度非常缓慢，即使使用很长时间，也不易觉察到这种转变过程。

随着温度的提高，原子扩散速度加快，球化过程就变得明显，性能渐趋劣化。

因此，长期以来20号钢组织中的珠光体球化程度常被广泛地用作使用可靠性的评定判据之一。

本标准的附录A、附录B都是标准的附录。

本标准的附录C、附录D、附录E、附录F、附录G都是提示的附录。

本标准由中国电力企业联合会标准化部提出。

本标准由国家电力公司电站金属材料标准化技术委员会归口。

本标准起草单位：华东电力试验研究院。

本标准主要起草人：励德成、徐俊、卜永康、沈金坤、刘琦。

本标准由国家电力公司电站金属材料标准化技术委员会负责解释。

1 范围本标准规定了火电厂用20号钢珠光体球化的评级方法。

本标准适用于按GB 3087、GB 5310标准供货的20号钢火电厂管道、管件在高温下长期使用后的珠光体球化等级评定，也适用于用20号钢钢板、条钢、型钢制造的构件在高温下长期使用后的珠光体球化等级评定。
