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.
Magnetic flow meter grounding rings.
The grounding ring typically installs on the upstream side of the magnetic flow meter.
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.
Result is usually not an inaccurate flow measurement but rather an unstable flow measurement that can make control difficult or impossible.
Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6.
Ground rings or lining protectors should be connected as shown in figure 5.
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.
Many of the exotic alloy grounding rings are maintained in stock in a variety of materials up to 6.
In this situation ground rings provide a path to shunt the current around the fluid in the magmeter.
Using two ground rings will provide a path to shunt the current around the fluid in the magmeter.
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.
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.
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.
Other sizes are.
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.
Current flow through grounding components may occur if.
The size of the grounding rings should always match the meter size as opposed to the original pipe size for installation with inline.
Type e grounding rings utilize customer supplied bolts rather then grounding wires or grounding straps.
The use method of grounding ring of the electromagnetic flow meter.
It is important to remember the purpose of the solution ground connection is to serve as a reference point of the flow measurement.
