Specifying water level transmitter with 4-20mA output requirements
Some questions to ask when defining the product requirements for a water level transmitter with 4-20mA output.
Installation type
How do you want to install the water level transmitter, will it be mounted to the outside of a water tank, lowered inside a water tank, or suspended from a platform above the water surface?
Water type
What kind of water will you be measuring, freshwater, seawater, drinking water, chlorinated water or wastewater?
Level range
What range of water level in metres or feet do you need to measure over?
If measuring a water tank, is the tank air tight or vented to outside air pressure?
Accuracy
How accurate does the water level measurement need to be?
Will it be used to determine the quantity of water, or to protect from overfill or underfill?
Electrical connection
Do you have a preference on what type of electrical connector and 4-20mA signal cable to use?
Will the water level transmitter be exposed to an indoor or outdoor environment?
Could the water level transmitter be temporarily flooded or will it be permanent submerged?
If a cable is required, how long does it need to be to connect to the water level measurement instrumentation?
Process connection
If the water level transmitter is going to be external to a tank, how do you intend to mount the sensor if it is going to be fitted to the outside of a tank, what type and size of thread or flange?
Temperature measurement
Would you like to measure the water temperature as well with a separate 4-20mA signal from the same transmitter?
