| сухое колено (The use of tubing (possibly heat traced and insulated to keep the product in a vapor state) running from the vapor space to the low side of the installed pressure transmitter(s). The transmitter(s) are used in the differential pressure mode. This method allows the transmitters to be calibrated with a lower pressure span. No top transmitter is needed, although one could be used to monitor the vapor pressure Метран) | |||
