MT86/MT86HT Flow Meter OPERATION
Fluid Components International LLC 9
3 OPERATION
Introduction
The flow meter has been configured and calibrated to custom specifications. Each flow meter contains distinct operating limits and units of
measurement. This section will show how to determine and manipulate the configuration of the flow meter.
The flow transmitter contains electrostatic discharge (ESD) sensitive devices. Use standard ESD
precautions when handling the flow transmitter. See INSTALLATION, page 3, for ESD details.
Enable Optional Totalizer Back-up Battery
There is a totalizer option for the flow meter. This option has a backup battery that keeps power applied to the memory that holds the
accumulated count during loss of power. There is a jumper on the back of the totalizer and display board that needs to be repositioned to
the ON position. See Figure 6 for the jumper location. The estimated life of the battery is 3 years of power off operation. The battery power
is drained only when the operating power is off and the battery power is on. During shipment and storage, the battery jumper is OFF to
conserve power.
The flow totalizer accumulates the total quantity of media that has passed the flow element over a specific time. Short two connector
terminals together on the display board to reset the flow totalizer display, see Figure 6 below for details. In applications where the operator
is required to reset zero, FCI recommends that these terminals be brought out to a convenient reset switch.
