Flow & BTU Energy Management
Model 1000
Microprocessor Flow computer
Four Inputs:	Differential Pressure D/P Static Pressure Temperature Optional

The use of the differential pressure drop across a restriction in the pipe regardless of the type has been the most popular method of volumetric flow rate metering for several years. This fine microprocessor based flow computer is designed specifically for use with differential pressure type flowmeter such as orifice plates, pitot tube, venture tubes, elbow taps, and many others. This model features powerful resident, non-volatile programs to automatically correct volume at flowing conditions to volume at standard conditions.

This model requires very few input "keyed" data in order to be put into operation. Since D/P calculations are generally done by others for the purpose of sizing the unit to the pipe there is no need for the Model 100 to repeat the same calculations. The user simply enters the input ranges for differential pressure, static pressure and temperature. If this is to be used on an orifice plate or pitot tubes used in the calculation are keyed into the unit. All necessary numbers are prompted on the LCD display and data is entered via a 16 position keypad on the front of the unit. The LCD also displays volumetric and percentage flow rates, totalized flow time and date.

A counter in the totalizer section of the computer converts the corrected flow rate to pulses which are accumulated on a front panel display providing continuous readout of total flow.

The model 1000 features EE prom, not requiring battery backup to retain entered constants. On power failure (loses time and internal counts).
