- the restriction 304/404 improves the measurement, since usually with the use of these flowmeters, the device pumping the liquid is arranged as suction points downstream, so to speak. This pump usually operates in a certain cycle, which generates a different negative pressure on the outflow side of the meter. Due to this changing negative pressure, a falsification of the measurement result can be brought about.
- the use of flow orifice 300/400 on the discharge side reduces this influence, in particular because the flow restricting throat 14, as nozzle aligned with the impeller 50, corresponds to the drainage diameter through the restriction 304/404.
- the element 300 or 400 has been referred to as a flow restrictor. It produces a pressure loss at the outlet and thus a reduced flow through its constriction 304 or 404.
- the diameter of the opening of the flow aperture is greater than or at least of the order of its length in the tube direction.
- the downstream pump can compensate for this pressure loss but;
- the flowmeter is installed on the suction side of the pump.
