Non Contacting Level Control
Really depends on what accuracy you need. If just to control a solenoid valve, you can use an ultrasonic measuring device. The best one I have found is manufactured by Milltronics Inc. Very accurate and reliable.

In the past I have used a microwave signal sensor to read materials on a conveyor, Thermo Fisher Granuflow DTR213Z. This sensor used two parameters to close contacts, material present and material in motion. Dual sensing was useful for controlling spray applications on conveyors.
In last few years Thermo has quit making this sensor. It was previously in the E+H line. Anyone know of a good replacement? I will look into Milltronics as well. ■
Non-Contact Conveyor TPH Measurement
Non-Contact Conveyor TPH measurement with 4-20mA output controlling a solenoid valve.
Query:
I am trying to control a water solenoid with 4-20mA output from the belt weigher or similar. Similar meaning instead of a belt weigher what can I use that will be able to control a solenoid valve - non-contact weigher/measurement.
What is required is an output that varies with weight/tonnage of the ore on the conveyor so the ample water is supplied. For example if there is less ore on the belt then less water is supplied. Current condition: ON/OFF solenoid so too much water on belts causing spillages and other secondary issues.
Also are there any non-contact measuring instruments that can be used to measure tonnes per hour instead of a normal weightometer? ■
