Differential Pressure Transmitters

Differential pressure transmitters measure the pressure difference between two points and can detect any slight pressure change between them. These devices are used to monitor for clogs in a pipeline, to determine the liquid level inside a tank in lieu of costly tank level mechanisms, or for low-cost flow measurement where pipe size may make flowmeters too expensive.
