Transfer factor

Range of the flow rate/signal characteristic curve, in which the flow rate does not significantly change despite an increasing input signal (EDIN 24 311).

Delivery flow pulsation

To measure the flow rate running through a defined part of the pipeline, there are a number of procedures, such as the displacement principle with flow sensors with oval rotor assembly , measuring tur

Maximum deviation of the average flow rate signal function from the straight line of the average flow rate amplification. Stated as a percentage of the nominal flow rate .

In the case of continuously adjustable valves: Dependence of the flow rate on the load pressure with the input signal as a parameter (DIN 24 311). The graphical representation is the flow rate/pressur

A distinction is made between: pressure-controlled : Area between minimum and maximum flow rate as a function of the pressure difference (inlet pressure minus outlet pressure): Q = f (p) under stated

Only for continuously adjustable valves: Degree of deviation of the average flow rate signal transfer factors of the positive and negative signal range. It is determined using the difference of both a

For two orifices with diameters d1 and d2 which are connected in parallel or in sequential, the diameter dE of a replacement orifice can be calculated. For sequential configuration the replacement ori

The heat emission PD of a reservoir is calculated from the temperature difference between the reservoir and the ambiance (To – Ta), form the heat-emitting area A of the reservoir and the heat transfer
