The world of flow The world of flow 3. Function Description This instrument can be used as a rate meter and as a pulse counter. The instrument has been pre-programmed in the factory and must be adapted to your process for both the rate meter function and pulse counting (see Section 5 – Programming). The instrument is ready for operation when the programming input is not wired. You can switch between Rate meter and Pulse Counter displays using the S/E key during operation at any time.

The world of flow The world of flow Measurement starts with the active edge at the counter input A. After the measurement time (1 sec) has elapsed, the measurement is completed with the next active edge, and the value is displayed in CHANNEL A. If no active edge appears within the “time out” period you have programmed, the rate meter is reset to zero. At frequencies > 1 Hz the average is calculated.

This display identifies the pulse counter (Channel B); it cannot be changed. 4. Press S/E again: You reach the next menu item. See the possible settings allowed in each menu from the following figures. Flashing display elements are shown in a lighter color.

The world of flow The world of flow Sensor Pulse Constant, Channel A – Rate meter Physical unit: l/h Physical unit: gal/s Physical unit: gal/min Physical unit: gal/h Physical unit: 1/s You can set the pulse constant of the sensor in the range of 1 to 99999. The sensor pulse constant provides the number of pulses per unit.
PAGE 8
The world of flow The world of flow Scaling factor, Channel A - Rate meter You may set the scaling factor (SF) in the range of 0.0001 to 99.9999 as explained for setting the pulse constant. The scaling factor is used when converting one physical unit to another (e.g., diameter to perimeter, liters to gallons).
