A pipe or tube that has a constriction with a relative long passage with a smooth coned entry and exit.
A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.
A switch intended to give a on/off signal when vibration level have reached a pre-set value.
A transmitter of which the output is proportional to a measured vibration.
An analysing instrument intended to determine the viscosity of a fluid.
A signal converter that is intended for converting an input voltage signal into an output current signal.
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.
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.
