Differential pressure instruments according to ISO 5167 are used in most industrial sectors. The available range of different throttling devices and materials allows measurement of many different fluids over a wide range of flow rates, temperatures and pressures.
Due to their standardization, the expected measurement results are manufacturer independent.
Design features, constraints and error limits of the various differential pressure flow elements are described in detail in the ISO 5167 standard. Listed below is a general description of the different elements that we offer.
