Fuji Electric's diaphragm seal retractable transmitter prevents production stoppages. Thanks to its integrated ball valve, the level transmitter and the process fluid can be isolated under load. The level transmitter can be removed without emptying the tank. This means that cleaning, maintenance, transmitter calibration or instrument replacement can be carried out at any time, without stopping the production process. This unique combination consists of a flush diaphragm level transmitter and a special ball valve. It guarantees accurate measurement, while allowing the process to continue without loss of production, thus increasing equipment availability.
