An instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.
A transmitter which output is relative to a measured voltage.
A flow meter that measures the velocity of a fluid in a pipe by detecting the frequency of vortices being shed from a specially shaped obstructing element in the fluid stream.
A transmitter specially designed to convert the signal in a vortex flow meter into a standardized output signal.
A wafer pattern valve that is a check valve with a wafer pattern valve body.
Which is flat and typically vertical suitable for separation.
A transmitter for weighing large quantities of material, and of which the output is proportional to the measured weight. .
A detecting element that can be the sensing element of an anemometer or wind gauge.
An analysing instrument intended to determine the wobble index of a gas.
