Electronic Flow Meters
Reference: N.F 4501/2011 12/30/2010, Location: Middle East
Category: Flowmeters
Scope of Work
It is required to supply electronic flow meters to measure the consumption fuel (Gases & Liquids) by boilers, furnaces, generators and flairs.
It must be done by Ex-d flow meters offered the Net and thermally compensated volumes to (15, 20) Cº and a pressure of 1.01325 bar.
The total quantity are 18 (eighteen) Flow meters.
