Flow computer for calculating compensated flow and thermal energy of steam, water and other liquid media and compensated flow of process gases with electronically registered results.
Wall-mounted case, power supply 230 V or 24 V.
Simultaneous consumption calculations in up to two different measurement systems (A, B, C) for separate process lines.
The computer enables:
compensated flow and energy measurement of unsaturated or saturated vapour and water according to IAPWS-IF97 guidelines,
compensated flow and energy measurement of other liquids, calculations are made within a range of tabular values entered by the user,
compensated flow measurement of process gases.
The computers can interact with the following types of flowmeters:
mass flowmeter,
volumetric flowmeter,
differential pressure flowmeter with approximation using root characteristic or according to an iterative algorithm, compliant with PN-EN ISO 5167 (only for water and steam).
The device has ten measurement inputs:
2 x RTD/I, two inputs adapted for connection of resistance temperature sensors (Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000) and transducers with a 0/4‑20mA current output,
1 x I, one input for interaction with 0/4‑20mA transducers only,
2 x I/PULS, two inputs intended for connection of transducers with a 0/4‑20mA current output or with a pulse output (range 0.001Hz … 10kHz)
4 semiconducting output relays: alarm and control functions, operation in pulse output mode with fixed pulse weight.
1 or 2 optional 4-20mA analog outputs.
Ports:
RS485 port: ASCII or MODBUS RTU protocol ,
Ethernet port: Modbus TCP protocol, Web server.
