FLOW INPUT
Select the type of square law flowmeter to be used with the
instrument.
Note:
This selection will only appear if one of the Square Law
selections were made in "FLOWMETER TYPE".
Selection:
ORIFICE, V-CONE, ANNUBAR, PITOT, VENTURI, FLOW
NOZZLE, BASIC SQRLAW/TARGET, WEDGE
Display: ORIFICE
SQUARE LAW FLOWMETER
Select the type of measuring signal produced by the flowmeter.
Selection:
DIGITAL, 10 mV LEVEL Voltage pulses, 10mV
trigger threshold.
DIGITAL, 100 mV LEVEL Voltage pulses, 100mV
trigger threshold.
DIGITAL, 2.5 V LEVEL Voltage pulses, 2.5V trigger
threshold.

INPUT SIGNAL
Set the low scale value for the analog input signal.
The value entered here must be identical to the value set for the
flowmeter.
Note:
• For flowmeters with analog/linear output, the flow computer
uses the selected system units for volumetric flowrate.
• The units for differential pressure flowmeters are
dependent on the system units selected for pressure:
- Imperial units [inches H2O]
- Metric units: [mbar]
