Do these transducer lines that are connected to the manifold need to be purged to get rid of the air? It seems like they should be, but then I was wondering how that was done if you need to put the plug into the manifold with thread sealant.
Good question..... Pressure is pressure.. It doesn't matter if it's water, gas, oil or air. They do make the transducers compatible with the product being measured. But an oil pressure transducer will measure air with no problem. It will compress, but only to the same pressure applied.
Actually, air trapped in the line will cushion pulses from pumps and that's a good thing for longer transducer life. Also, the next time you remove the fitting, you will have a clean disconnect.
