A cooler and an air cooled heat exchanger that is a tall structure through which air circulates by convection.
An element located in a flowstream using the Coriolis principle to measure the flow.
A mass flow meter that uses the Coriolis principle to measure a mass flow rate through the meter.
A detecting element that is a piece of suitable metal meant to corrode and give an indication of the corrosion rate.
A detecting instrument intended to measure, indicate and/or produce a signal which represents the rate or degree of corrosion.
A transmitter that is producing a standardized output signal dependent of a received input signal from a corrosion sensor.
A detecting instrument that counts, especially an electronic or mechanical device that automatically counts occurrences or repetitions of phenomena or events.
Connecting with a coupling or coupler.
A mill that uses pressure or impact to reduce the particle size of solid materials.
A signal converter that is intended to convert one current signal to another current signal.
A signal converter that is intended to convert an analogue signal (4 - 20 mA) to a proportional linear pneumatic output signal.
A signal converter that is intended to convert a current input signal to a proportional voltage output signal.
An instrument transformer in which the secondary current, in normal conditions of use, is substantially proportional to the primary current and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.
A transmitter that transmits an analogue electrical current.
A device that damps, typically a valve or plate (as in the flue of a furnace) for regulating the draft, or a device to stop vibration, typically a shock absorber or snubber.
A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.
A control valve that is intended to operate at high temperature, and admit water into a deluge system.
An analysing instrument intended to determine the density of a substance.
An analysing instrument intended to determine the dew point of a substance.
A facility for measuring dew point and transmitting a signal representing the measured temperature.
A diaphragm 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 flow transmitter providing an output signal that is proportional to the flow inputs from a differential pressure flow meter.
A gauge that is intended for measuring and indicating pressure differences.
A level transmitter that is measuring liquid level by sensing pressure difference between two points, e.g. the hydrostatic pressure at the bottom of a tank to the atmosphere pressure.
A pilot switch intended to switch or give an on/off signal when the measured differential pressure has reached a pre-set value.
