Gas and steam flow ModBUS computer
The KET-CEV-100 is a gas and energy steam flow calculator, which measures the flow rate and instantaneous value in open circuits.
Thanks to compensation equations, it can measure both natural gases (NX-19) and ideal gases (Redlich-Kwong), as well as saturated and superheated steam (IAPWS-IF97).
It accepts analog and/or impulsive flow signals from vortex, turbines, calibrated flanges, pilot, cone-meter, thermal mass.
It is equipped with analog outputs and relays, an RS485 interface with ModBUS RTU protocol up to 32 slaves.
Easy to configure and program using the front keys and the large display.
With Data Logger function, it records data every minute for 24 hours.
