Figure 3-4. Meter Body Ground
Grounding the Meter Body
The meter body must be properly grounded. The lack of an effective earth
ground at the meter body will result in metering errors caused by extraneous
voltage at the electrodes.
Anderson Instrument Company recommends attaching a dedicated wire from
the 5mm (0.200") diameter ground lug on the side of the meter body to an
effective earth ground connection point. The ground wire should be of
sufficient wire gauge to provide zero resistance to the actual earth ground
connection point.
Connection Cables
Anderson Instrument Company provides two factory-ready connection cables
with the flowmeter. The electrode signal cable is a gray, 3-conductor
shielded cable (see Figure 3-5). The coil drive cable is a black, 2-conductor
shielded cable (see Figure 3-6).
Note: Standard cable length is 25 feet. It is specially designed for
the IZMSG Compact Flowmeter. The ends of the cable are
prepared according to factory specifications. Never substitute
any other cable for a factory-supplied cable. Do not splice
connection cables. Contact the factory for cable length
requirements that exceed 25 feet.
