a P/I transmitter is used to control a gas valve position , but i'm facing a problem of damaging these transmitter they are based on a coil....if it is from the PLC Allen Bradley (4-20 ma) suggest me the best protection for my loop to keep the coil from harm .
i have pressure/current converter SRI983 where its main electronic component is the coil that changes current to pressure or the opposite .and this transmitter is 24V and 4-20ma .
but i'm facing a big issue of damaged coils for a years and now someone suggested a solution to install...
I want to realise a project of installing Ultrasonic transmitter and display the quantity of gas in my control room, and to know the quantity of the day and month and year.
Need advice about flow control that can display that.
