Differential pressure flowmeter
Differential pressure flow meters are standardized and proven flow meters.
Their calibration is thus superfluous and their accuracy guaranteed according to the standards in force (ISO 5167, ISO / TR 15377, ASME-MFC 3M ...). They have the advantage of being reliable, economical and robust. They can be used for all types of fluids in liquid, gas and vapor form.
Specific solutions can be proposed in order to ensure reduction of straight lengths (multi-hole orifice plate), reduction of possible leak sources (compact flowmeter), increase of accuracy measurement (meter run), increase of turn-down ratio (double transmitter solution) or increase of orifice life time in presence of corrosive and agressive fluids (specific coating of the orifice).
