3.1 Programming
In order to obtain a real flow rate and volume, the pulses/litre factor specified in the flow
meter must be programmed.
In all the programming screens, the key “Escape” exits the screen without saving the data
into the memory, even if changes in the digits have been made or not .
By pushing the key “Enter”, the display will change to the programming mode. In this
mode there are 7 digits (four whole numbers and three decimals). The value that must be
introduced is the pulses per litre factor given on the label of the COVOL or Turbine.
To do this, pressing the key “Up arrow”, the blinking digit will increase. If the value
reaches 9, by pressing this key the digit returns to zero.
Once the desired value of the digit is achieved, by pressing the key “left arrow”, the cursor
will pass to the next digit to be modified. On the seventh digit, by pressing this key the
cursor will pass to the first digit on the display.
When the value of the pulses per litre is correct, by pushing the key “Enter”, the value will
be automatically saved into the memory and the units selection screen will appear.
To change the flow rate units, the key “Up arrow” must be pressed. To change the
totalized volume units, the key “Left arrow” must be pressed.
The possible flow rate and totalized volume units are the following:
Flow rate:
There are 9 combinations made from 3 volume units and 3 time units.
Volume / time
l (litres) / s (second)
m3 (cubic meters) / m (minute)
ga (US gallons) / h (hour)
Totalized volume:
There are 3 possible volume units, l (litres), m3 (cubic meters), ga (US gallons)
Note: 1ga = 3.785 litres.
With the working units chosen, by pressing the key “Enter”, we go to the current loop
programming.
