To calculate the flow rate (l/min) for a measured current I(mA) then:
3.4.2 Pulse output
Pulse output configuration
Two parameters can be configured from the PULSE OUTPUT menu:
• Volume of fluid per pulse.
• Pulse width.
1. With the instrument operating in the FLOW
READING mode, press the Pulse function
key to access the PULSE OUTPUT screen.
2. Ensure that the Output is Off.
3. Select Vol per pulse and press ENTER.
4. Enter the required value. (In the example
shown, a pulse is produced every 10 litres
of flow).
Note: The Vol per pulse can only be changed if the Pulse Output is Off .
5. Select a Pulse width (in ms) to suit the particular application – e.g. electro-mechanical counter. Refer to
the manufacturer’s data sheet for the minimum pulse width.
6. Select Exit and press ENTER to return to the FLOW READING screen.
How to turn the pulse output OFF/ON
