Magnetic Flow Meter Grounding Rings

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.

Magnetic flow meter grounding rings.

Current flow through grounding components may occur if. Use of grounding rings significantly reduces electrical noise and may be necessary for proper operation of electromagnetic flow meters installed in lined or non. Ground rings or lining protectors should be connected as shown in figure 5. It is important to remember the purpose of the solution ground connection is to serve as a reference point of the flow measurement.

Multiple magmeters are used in a system. 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. In some occasions it is not suitable to increase the grounding ring. 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 conductive pipes. In this situation ground rings provide a path to shunt the current around the fluid in the magmeter. Other sizes are. Result is usually not an inaccurate flow measurement but rather an unstable flow measurement that can make control difficult or impossible.

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. Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6. Type e grounding rings utilize customer supplied bolts rather then grounding wires or grounding straps. In addition to providing the required solution ground placing this grounding ring on the upstream side of the flow tube also provides a fair degree of liner protection to the leading edge of the flow tube s liner when used in moderately abrasive applications.

The grounding ring typically installs on the upstream side of the magnetic flow meter. This lets the magnetic flowmeter read a stable zero flow and achieve accurate measurement in flow conditions. The size of the grounding rings should always match the meter size as opposed to the original pipe size for installation with inline. Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6.
