n: the housing of an automatic tank gauge. It may include the indicator aIxI the transmitter.

n: it refers to telephone besides driller and the horn with transmitter on the monkey board.

n: a tightly banded scroll of special steel that vibrates when a magnetic field is applied to it. The vibration of the scroll sets off a transmitter, which is alternately switched on and off at 15 to 60 times per second. The transmitter causes compressional sound waves to travel through the formations surrounding the borehole. Each formation material will exhibit its own characteristic effect on the elastic wave propagation.

n: (MWD) 1. directional and other surveying during routine drilling operations to determine the angle and direction by which the wellbore deviates from the vertical. 2. any system of measuring downhole conditions during routine drilling operations.

n: a mothod of measuring parameters downhole and sending the results to surface without interrupting routine drilling operations.a special tool containing sensors,power supply and transmitter is installed as part of BHA (q.v.).the information is transmitted

downhole logging while drilling. “Logging While Drilling” is one form of measurement while drilling" - to differentiate it from mud logging, wireline logging, etc. See Logging While Drilling.

n: an instrument that receives signals from a transmitter.

n: see transmitter.

n: solid or stranded wire or cable that connects a float to a tape or that drives a dial indicator or transmitter.

n: an electronic device that counts each pulse generated by a meter transmitter.

n: a single receiver used with a remote transmission system to permit the use of one or more tank transmitters so that selective liquid level readings can be obtained by switching from one tank to another. Compare single-tank remote gauge.

n: a remote transmission system for determining liquid level in tanks that require a separate receiver for each tank transmitter. Compare selective-tank remote gauge.
