differential pressure flow meter

PTF600 Pitot tube flow meter is COMATE’s heavy duty designed flow meter for wet and dry air. It has an wide turn down DP transmitter which ensures it a 33:1 wide measurement range and better stability. It has an unique water-proof design which can solve the problem that caused by condensing water in capillary.

PTF600 Pitot tube flow meter also has integral temperature and pressure compensation, so it can measure standard flow, temperature and pressure also.
