PlatformsProver HMI, master meter comparison, valve sequencing
The brief
Inelgas Metering Systems needed an automated prover to verify that custody transfer meters read true.
What we built
The HMI routes flow through the prover, compares master meter and test meter volumes across repeat passes, sequences the valves and computes the meter factor.
How a proving run works
The HMI routes flow through the prover, sequences the valves and compares master meter and test meter volumes across repeat passes. From those passes it computes the meter factor.
A record of every run
The operator can check the meter factor on demand and keep a record of every proving run.
Outcomes
