Anyone have some experiences with Flowmeters?
Typically you are only given normal process flows from the material-energy balance calculations. The instrument range is typical chosen at factor of 120-140% larger than normal flow for d/p meters to account for variations in the pump capacity and valve swings, and so on.

Radar level transmitter problem
Foaming presents problems in some services. If you get good reading with reduced filling rate, then you'll have to reduce the rate of filling.

Radar level transmitter problem
This is a common problem. The measurement is only suited to ideal fluids with splashing, foaming, or changing reflectivities. You need an alternate measurement.

if the air leak is pushing the liquid away you are okay. ORings do not use rubber as a rule.

Emerson magnetic flow meters 8700 peoblem
That is a typically a pipe mounted device, flow through, not "imersive." As the electronics drive the magnetic coil used, you'll need to contact your supplier, for basic trouble shooting advice.

fisher pcv installed in petrol road loading line
The samson valves were pneumatic(air) operated, the Fisher self contained, with actuation by the process fluid. In liquids the 6351 regulator must be used, but the risk is possible leakage of diesel from the actuator. High temp seals must be used if you have temperatures>50C

Here is CO's pdf with an arrow showing the direction of flow. Make sure the flow is aligned with the arrow tag on the valve

you may be dealing with a winding failure, check your motor shop, and do the winding insulation testing when you get a chance.
