On site we have differential pressure transmitters used to measure drum level, at pressures of 110 bar, 25 bar and 4 bar respectively. the sensing legs of the DP trx have demineralized water. In the winter, the trace heating is not enough so when there is no generation the water lines get frost and the signal has problems. If we put glycol in the sensing legs, then probably we will need to make again the zero of the trx? is there any problem since glycol is more heavy than water?
