Description:
The electronic evaluation unit (register) consists of a microprocessor board powered by a
lithium battery. It can be programmed in litres, pints, quarts or gallons and adds in litres or
gallons.
A calibration factor and a unit of measure are programmed during a factory test. Unlike
mechanical units, these can be electronically recalibrated in the field if necessary. A 6-digit
LC display with three decimal places shows the exact amount of liquid flowing through the
meter. The register is protected from normal wear and tear by a robust, shockproof
housing.
Operation:
The magnets integrated in oval gear counters send pulses to the register.
The register is in sleep mode until pulses arrive. The pulses are generated by the liquid
flowing through the meter.
The register shows the current flow rate, the subtotal and the total.
The resettable totaliser has a 6-digit display with three digits after the decimal point. If the
measured quantity exceeds 999.999, the display jumps over. Then only 2 digits behind the
decimal point 9999.99 are displayed and so on up to the maximum value of 999999. After
999999 is reached, the totaliser starts again with 0.000. When the reset button is pressed,
the totaliser is reset to zero. The register also has a resettable total counter. To reset this,
the total and reset keys must be pressed simultaneously ("Total" key pressed and held,
"Reset" key pressed). This can be used for several subtotals.
The non-resettable totalisers have 11 digits and count arbitrarily in either gallons or litres.
