Selecting a Location
The 2552 requires a fully developed turbulent ? ow pro ? le for accurate measurement. Selecting the correct location in the piping system is critical to the performance of the magmeter.
Locate the magmeter where air bubbles will not contact the electrodes.Placing the sensor in a vertical section of pipe, with ? ow going UPHILL is the ? rst choice for this requirement.
The piping system should be designed to keep the sensor wet at all times.
In applications where the conductivity of the process liquid is less than 100 μS, magmeters should be allowed to soak in a full pipe for 24 hours before operation.
3.1 Vertical Installations Recommended Locating the sensor where the ? ow is upward protects the sensor from exposure to air bubbles and may offset upstream turbulence O.K.
Located the magmeter in a "trap" to prevent air bubbles and to keep the electrodes wetted for best performance.
Air pockets and bubbles will travel at the top of a horizontal pipe, so avoid vertical installations.
Sediments and debris that collect at the bottom of a horizontal pipe will interference with the operation.

4. General Installation and Grounding Tips
4.1 Sensor conditioning
The Magmeter output signal may be unstable immediately after installation. Allowing the sensor to soak in a full pipe (or in any container of water) for 24 hours will stabilize the performance.? Very low conductivity ? uids may require a longer conditioning period.? The Magmeter may not operate properly in ? uids where the conductivity is less than 20 μS/cm.4.2 Grounding
The 2552 Magmeter is unaffected by moderate levels of electrical noise, especially if installed in a properly grounded metal piping system. However, in some applications it may be necessary to ground portions of the system to eliminate electrical interference. The grounding requirements will vary with each installation.
One or more of the following steps may be applied if the 2552 Magmeter is affected by electrical noise:
c Connect a wire (14 AWG/2.08 mm
2
recommended) from the ground terminal screw on the sensor nut directly to a local Earth
ground.
d Install ? uid grounding devices immediately upstream and downstream of th
e Magmeter.
Connect the ? uid grounds to the Earth ground terminal on the 2552. Use ? anged grounding rings or metal electrodes on plastic pipes, or metal clamps on metal pipes. Fluid grounds must be in direct contact with the ? uid, and as near to the Magmeter as possible.
e Connect the SHIELD conductor to Earth ground near the instrument.

4.3 Preparing for Installation
The alignment of the electrodes in the pipe and the insertion depth of the electrodes in relation to the inside diameter of the pipe are critical to the successful operation and calibration of the system. The brass rod that is supplied with the 2552 is used to assist with this requirement.
4.4 H-Dimension
The H-dimension is the distance from the TOP OF THE PIPE to the BOTTOM OF THE BRASS ROD.
The tables on pages 8–11 include the H-dimension for two of the most common pipe schedules from DN50 to DN2550 (2 in. to 102 in.).If the pipe is not represented in the tables on pages 8–11, use the procedure below to determine the H-dimension.The goal of the procedure is to place the Magmeter electrodes 10% inside of the pipe
Hardware stack height is important
The H-dimension represents the total height avaliable for the installation hardware.
If there is insuf ? cient clearance to accommodate the hardware, select a longer 2552 Magmeter or modify the hardware to reduce the stack height.

Sensor Selection Guide
The 2552 Magmeter can be installed into a variety of pipe sizes. Follow the steps below to ensure that you choose the right sensor for your application.
Step 1: Determine how the sensor will be installed ? For retrofit installations, the ball valve must be at least a 1? in. (or 1? in. for 2552-3) full port valve. The stack height, or “A” dimension (see Fig. 2), is the overall height from the top of the pipe to the top of the ball valve, or the top of the highest point of the stack before the sensor is connected.
B. For Hot-Tap installations:
The stack height of the ball valve, nipple weldolet (threadolet) and pipe adapters should be determined before the sensor is purchased.
? For new installations, Signet
recommends a 1? in. or 1? in. full port ball valve, a short nipple and a weldolet (threadolet). The stack height or “A” dimension (see Fig. 2) is the overall height from the top of the pipe to the top of the ball valve.A. For standard (non Hot-Tap) installations:
The height of the weldolet (threadolet) and pipe adapter(s) should be determined before the sensor is purchased.?
For retrofit installations, the stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to the highest point of the stack before the sensor is connected.
?
For new installations, Signet
recommends a weldolet (threadolet) and an adapter to accommodate the 1? in. (or 1? in. for 2552-3) sensor process threads. The stack height, or “A” dimension (see Fig. 1), is the overall height from the top of the pipe to the highest point of the stack.
Step 2: Determine how the sensor will be installed
Once the “A” dimension is determined, go to the sensor selection table and find your “A” dimension on the left column. Next, find the appropriate pipe size at the top of the chart. To determine the correct sensor size locate where the pipe size column meets the max “A” dimension row.
