Working Principle Field DP, pressure transmitter 4 to 20 mA and RTD temperature signals enter terminals; conditioning after 16-bit ADC sampling. Frequency channels count turbine meter pulses. Data is uploaded over Modbus to the flow computer, which computes volumetric and energy flow per natural gas formulas. LEDs indicate channel status.
Installation Requirements
- Insert chassis slot with power off
- Shielded twisted pair signal wires
- Three-wire RTD compensation
- Chassis grounding
- Temperature -40 °C to +70 °C
- Configure channels in flow computer software after power-up
- Custody metering requires periodic calibration
Precautions
- Do not hot-swap online
- Custody metering calibrated per regulations
- Sensor accuracy matches module
- Store spares in anti-static moisture-proof packaging
- Configure channels after replacement
- Periodically calibrate zero
