A velocity flow meter which uses the principle of thermal conductivity to measure volume flow rate.

A pair of electrical conductors of dissimilar materials, joined at one end (the measuring or hot junction), which produces an electromotive force (e.m.f.) due to the Seebeck effect in a circuit formed by connecting the other ends of the dissimilar materials used (the reference or cold junction) to a device for measuring e.m.f. Def. acc. to IEC 902 1987.

A transmitter specially designed to convert the signal in a turbine meter into a standardized output signal.

A flow transmitter providing electrical outputs that are proportional to the flow inputs from an ultrasonic flow meter.

A level transmitter that is using ultrasonic sound to continuously monitor the level of a liquid or particulate matter in a tank or vessel.

A transmitter specially designed to convert the signal in a vortex flow meter into a standardized output signal.
