wire sizing for connecting flow meter to Venus GX

Hello,


I have purchased a flow meter which can be connected to the Venus GX. Unfortunately this flow meter is around 50m away from the Venus GX. I am aware that the wiring will need to be of a greater diameter due to voltage drop.

Does anyone have an idea what the diameter of the cable should be? From a number of calculators it seems that 1.5m2 cabling is sufficient.

Thanks

Hi @casper. Without knowing the voltages involved or the specifics of the device itself, I'm personally not in a position to present you with a useful answer. Maybe you can elaborate? Where does the flow meter obtain it power?

Hello @ejrossouw


Thanks for the quick response. The flow sensor is a dry contact 2 wire flow sensor and therefore does not draw current itself. It simply closes the circuit for every 1 litre of water that passes through the meter.

A quick update here for anyone who would like to run a flow meter 100m away from the Venus GX. The flow meter (pulse meter) works fine when connected to the digital input of the Venus GX and with a 0.5mm2 cable. The Venus GX is not missing any pulses and the readings are correct.

Hi Casper, can you share which flow meter you have used? I am looking to connect a water consumption meter to the Venus GX as well

@casper I am also keenly interested in what flow meter you are using. Please do tell! :)
