Cabinet Power - Truck
Power to the worklights and Flowcom comes from the 12
volt junction box near the battery box. Within the junction
box is a relay that is energized with the truck key in the
ON or ACC position, providing cabinet power. The 10-amp
breaker protects the circuit.
These are Rosemount Pre-Set Dierential Pressure
Transmitters used on the Orca system. They are connected
to the meter section and the Flowcom meter system. The DP
transmitters measure a change in pressure (pressure drop)
across the meter section and relay this information to the
Flowcom meter system in a 4-20 milliamp signal.
RTD - Resistance Temperature Device
The resistance temperature device (RTD) is located upstream of
the meter. The probe is threaded into a port so it can accurately
measure the temperature of the liquid. The resistance of the
element at the end of the probe varies with temperature. The
RTD is used to measure accurately the temperature of the liquid
being metered. Based on this temperature, a density is assigned.
Flowcom Flow Meter System
The Flowcom
®
Flow Meter System is used for calculating,
integrating, system controlling, and displaying the mass ow.
