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 user’s
pipeline
Joule A unit of energy equal to one watt for one second. Also
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
μ 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)
ρ
act
The density of a fluid at the actual temperature and
pressure operating conditions
ρ
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 platinum
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
PV Liquid vapor pressure at flowing conditions (psia or bar
absolute)
