I J K L
In-Line Flow Meter A flow meter which includes a short section of piping
which is put in-line with the user’s piping.
Insertion Flow Meter A flow meter which is inserted into a hole in the us-
er’s pipeline.
Joule A unit of energy equal to one watt for one second. Al-
so equal to a Newton-meter.
LCD Liquid crystal display.
M N O P
m Mass flow rate.
mA Milli-amp, one thousandth of an ampere of current.
 Viscosity, a measure of a fluid’s resistance to shear stress.
Honey has high viscosity, alcohol has low viscosity.
nm3/hr Normal cubic meters per hour (flow rate converted to
normal conditions, as shipped 101 kPa and 0° C).
User definable.
P Permanent pressure loss.
P Line pressure (psia or bar absolute).

act
The density of a fluid at the actual temperature and
pressure operating conditions.

std
The density of a fluid at standard conditions (usually
14.7 psia and 20° C).
Permanent Unrecoverable drop in pressure.
Pressure Loss
Piezoelectric Crystal A material which generates an electrical charge
when the material is put under stress.
PRTD An resistance temperature detector (RTD) with plati-
num as its element. Used because of high stability.
psia Pounds per square inch absolute
(equals psig + atmospheric pressure). Atmospheric
pressure is typically 14.696 psi at sea level.
psig Pounds per square inch gauge.
