I have an OEM customer that wants to open / close a proportional valve based directly from a liquid level in a tank. We are proposing an ultra sonic level transmitter giving 4-20 into a PLC or converter card with direct PWM 600ma proportional output to valve. Their question is if ultrasonic is most precise type for this app. Any input from existing apps greatly appreciated. Thanks in advance.
