A variable area flow meter which consists of a tapered tube of glass with a float inside that is pushed up by flow and pulled down by gravity.
A detecting element that is intended to sense rotational speed.
A sample loop adds a predetermined volume to the process.
A physical object intended to be used to collect and contain representative specimens or selections.
A detector intended to detect sand in a fluid.
A manual control switch which has more then two possible positioning states.
A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.
A physical object that is transparent and intended for viewing a vessel or piping system interior.
A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.
An electric signal transducer that is intended to convert one type of standardized transmission signal into another.
An acoustic device producing a loud sound as a signal or warning.
A slide valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.
A smart meter is an electronic device that records information—such as consumption of electric energy, voltage levels, current, and power factor—and communicates the information to the consumer and electricity suppliers.
A devices that measure and communicate water usage from consumer to provider to facilitate water management and proper billing.
A detector that is intended to sense smoke.
An electromagnetic coil, which is a cylindrical coil, the length of which is much greater than its transverse dimensions and which is used to produce a magnetic field.
A valve that has linear action which is fitted with a solenoid for quick operation.
An analyser intended to determine a mixture of solid particles in liquids or solid or liquid droplets in air.
A meter intended to measure a sound pressure level.
An analyser intended to determine specific gravity's of materials. Typically of liquids.
A switch intended to give a on/off signal when the speed have reached a pre-set value.
A transmitter that is producing a standardized output signal dependent of a received input signal from a rotational speed sensor.
A check valve that is a check valve where the closure member is a disc which swings freely on a hinge and which opens automatically when flow is established and closes automatically when flow ceases or is reversed.
