In-Line Flow Meter A ow meter which includes a short section of piping

which is put in-line with the user’s piping

Insertion Flow Meter A ow 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 ow rate

mA Milli-amp, one thousandth of an ampere of current

 Viscosity-a measure of a uid’s resistance to shear stress.

Honey has high viscosity. Alcohol has low viscosity.

nm3/hr Normal cubic meters per hour (ow rate converted to

normal conditions, as shipped 101 kPa and 0° C). User

denable.

∆P Permanent pressure loss

P Line pressure (psia or bar absolute)

act

The density of a uid at the actual temperature and

pressure operating conditions

std

The density of a uid 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 owing conditions (psia or bar

absolute)
