Equipment
Equipment that requires this document type.
vibration transmitter
tag class

A transmitter of which the output is proportional to a measured vibration.

viscosity analyser
tag class

An analysing instrument intended to determine the viscosity of a fluid.

voltage to current converter
tag class

A signal converter that is intended for converting an input voltage signal into an output current signal.

voltage transformer
tag class

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.

voltage transmitter
tag class

A transmitter which output is relative to a measured voltage.

vortex flow meter
tag class

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.

vortex flow transmitter
tag class

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

wafer check valve
tag class

A wafer pattern valve that is a check valve with a wafer pattern valve body.

weight transmitter
tag class

A transmitter for weighing large quantities of material, and of which the output is proportional to the measured weight. .

wind sensor
tag class

A detecting element that can be the sensing element of an anemometer or wind gauge.

wobbe index meter
tag class

An analysing instrument intended to determine the wobble index of a gas.

Registers
