Scroll List
The user’s desired display list which can be presented on the two list display on Line 1 and/or L2 when the SCROLL key is
depressed.
Self Check
A diagnostic sequence of steps a unit performs to verify it’s operational readiness to perform it’s intended function.
Service Test
A diagnostic sequence requiring specialized test apparatus to function to verify system readiness.
Setpoint
An alarm trip point.
Simulation
A special operating mode for an output feature which enables a service personnel to manually exercise the output during
installation or trouble shooting operations.
Square Law Flowmeters
Types of measurement devices which measure differential pressure across a known geometry to make a flow measurement.
SQR LAW (Square Law w/o SQRT)
A square law flow measurement device equipped with a pressure transmitter with out a integral square root extractor.
SQR LAW-LIN (Square Law w/ SQRT)
A square law flow measurement device equipped with a pressure transmitter with integral square root extraction.
SQR Law 16PT (Square Law 16pt)
A mathematical approximation to a square law device where the discharge coefficient is represented as a table of DP Factor
vs Reynold's Number.
Steam Delta Heat
A computation of the net heat of saturated steam equal to the total heat of steam minus the heat of water at the measured
actual temperature.
Steam Heat
A computation of the total heat of steam.
Steam Net Heat
A computation of the net heat of steam equal to the total heat of steam minus the heat of water at the same saturated
temperature.
STP Reference
The user’s desired pressure and/or temperature to be considered as the reference condition in the computation of fluid
properties or corrected volume conditions.
TAG
An alphanumeric designation for a particular instrument.
Time Constant
An averaging filter constant used to reduce bounce on the analog output. The high the number the slower the response, the
greater filtering.
UVC
Universal Viscosity Curve is a representation of the calibration factor for a turbine flowmeter. It is expressed as a table of K-
Factor as a function of Hz/CSTKS.
Viscosity Coef
A parameter in an equation which is used to estimate the viscosity as a function of temperature.
