6.1.2 Device Description
Each AMETEK Drexelbrook Universal IV CM-DC system consists of a
Density Compensation unit
- Power - four-wire
- HART 7.0 4-20 mA
- Modbus
UIV CM Water Cut RF Admittance transmitter
-with a 700 series sensing element
Capacitance is transmitted to the DCM from a UIV CM via HART 5.0.
Required density, temperature and flow rate data are transmitted to the DCM via
Modbus from an external source such as a Coriolis meter.
Configuration and calibration of the DCM is accomplished via the onboard keypad
and LCD display
Or
Remotely by a PC running STExplorer T.M. software with a HART modem
