Magnetic Flow Meter Grounding Rings

Grounding rings are flat wafer style rings designed to be installed between the flanges and a mag910 e mag920 or mag930 series inline electromagnetic flow meter flange face.

Magnetic flow meter grounding rings.

In this situation ground rings provide a path to shunt the current around the fluid in the magmeter. Multiple magmeters are used in a system. The use method of grounding ring of the electromagnetic flow meter. Use of grounding rings significantly reduces electrical noise and may be necessary for proper operation of electromagnetic flow meters installed in lined or non.

The grounding ring typically installs on the upstream side of the magnetic flow meter. Use of grounding rings significantly reduces electrical noise and may be necessary for proper operation of electromagnetic flow meters installed in lined or non conductive pipes. For example grounding rings are very effective when utilized before and after a magnetic flow meter fitting between flanges to ground out unwanted signals in the fluid that can cause inaccuracies in the flow meter s readings. Ground rings or lining protectors should be connected as shown in figure 5.

Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6. This lets the magnetic flowmeter read a stable zero flow and achieve accurate measurement in flow conditions. Current flow through grounding components may occur if. Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6.

Other sizes are. Type e grounding rings utilize customer supplied bolts rather then grounding wires or grounding straps. The size of the grounding rings should always match the meter size as opposed to the original pipe size for installation with inline. Using two ground rings will provide a path to shunt the current around the fluid in the magmeter.

For example when measuring strong corrosive medium the pipe will be made of pvc or ptfe plated electrode which is precious metal especially for large diameter. For example grounding rings are very effective when utilized before and after a magnetic flow meter fitting between flanges to ground out unwanted signals in the fluid that can cause inaccuracies in the flow meter s readings. It is very important to connect both ground rings to the sensor case to minimize the current flow through the process fluid near the electrodes. It is important to remember the purpose of the solution ground connection is to serve as a reference point of the flow measurement.
