Initially on boiler drum level there is one transmitter for controlling & monitoring of water level & three trip switches were used for boiler tripping on low level.
My question is if boiler manufacturer provide all drum level securities with DP type level transmitters, is there any code & standard available to restrict on selection of transmitters or switches on boiler drum for level securities or controlling?
