The 7MF0340… must be mounted below the minimum water level of the system. It is recommended that the reference leg of the system is piped into the (-) port on the 7MF0340… transmitter. During initial setup it is important to ensure that the reference leg has been filled manually. The reference leg must remain full during operation. When used in a steam vessel this is achieved with a condensate pot which remains completely full due to the condensing steam. It is necessary to have an accessible location at the top of the reference leg and condensation pot system to manually fill the reference leg if necessary. The 7MF0340… should be mounted in the vertical position. For easy installation and setup, it is highly recommended to use a three-valve manifold. During the startup process the 7MF0340… should be bled of air. This can be done by loosening the plugs opposite of the process connections when the vessel is not under pressure. Once a steady stream of liquid is visible the plugs can be retightened. Since some water may have been drained it is important to refill the reference leg to replace any lost liquid.

The RHT-WM-485-LCD and RHT-DM-485-LCD transmitters include high precision and stability sensors for measuring temperature and relative humidity. They are microprocessed devices and, therefore, allow being entirely configured through a RS485 interface, using the Modbus RTU commands. The DigiConfig allows the configuration of all transmitter features as well as its diagnostic procedure.
