7.5 Connecting to TLV EC351 Flow Computer
This device can be used in combination with the flow indicator EC351. The correct-
ed flow rate of fluids whose temperature and pressure change (superheated steam,
air) can be displayed by combining with EC351 and a pressure sensor.
As for the connection with this device, the output and signal are associated as
follows as standard.
EF200F-C Settings
Assign pulse output 1: Pulse output: Mass flowrate (pulse output settings
→ See 10.4.6
(Current output settingas → See 10.4.5)
(pulse/frequency/switch output settings
→ See 10.4.6)
EC351 Settings
Function group: FLOW INPUT
Function: K-FACTOR
Selection: Set the specified values in the table below according to the size of the device.
Pulse width: 5 ms
Volume unit: L (litre) or dm3 (system units settings → See 10.4.2)
Value per pulse: Set the specified values in the table below according to the size of
the device.
Flowrate can be displayed on the EC351 without using the EF200-C analog output.
Connecting an external correction sensor to EC351 searately is necessary when displaying
the value converted to mass flow rate on the EC351.
