submersible pump head measurment

I hate having too much electric stuff down the hole. Can't you just mount your measuring device in a convenient spot outside of the well, and add the depth to the pump to the readings?

I just re-read the original question and realized that I read "submersible pump head" too quickly and interpreted it as "submersible head pressure".

If one needs to measure the level of the well water, using a submersible gauge pressure transmitter is one way to do so, and the sensor needs to be down the hole to make the measurement.

But, if the measurement needed is pump head, then yes, locating the pressure transmitter at the top, up and outside of the well, and adding in the elevation head would provide a good measurement. All the associated problems of having an inaccessible transmitter down in a well hole would vanish.

As the current vernacular goes: my bad.

Wouldn't the level of water in the well above the pump be considered suction head? Reading water level is important, can be done with a capacitance device. A pressure sensor at the pump will also tell you water depth above the pump.

That's exactly the way it is done in countless borehole water installations across the globe.
