We have Extended diaphrgm DP type level transmitters made of Yokogawa India ltd. in our sugar refinery, but we don't have HART communicators here. I found that in our Vacuum Batch pans the level transmitters are under range. I just want to change the upper range value of that DP level tranmitter. As I don't have HART communicator I have use the range setting switch available in the integral display. But if I go through in that way I have calibrate the transmitter after taking out from the pan. Is it possible to set only the upper range value with the same range setting switch in online when the boiling is going on? Kindly advise me.
