Hi, we are using Vortex flow meter of Emerson Make in Syn gas flow line in ammonia plant. Flow meter measuring range is 0-30000 Nm3/Hr. Normal flow rate is 23000 nm3/hr. We observed that flow meter reading having fluctuation up to 1000-1500 Nm3/Hr in normal running condition. This flow meter is having remote mounted transmitter. We changed sensor, its cable up to transmitter but still have variation in flow. As per process, there is not fluctuation in syn gas flow.
please guide what to check further to resolve problem.
