round housing ng 100 and 160 mm for chemical use differential pressure Δp can be directly read off Description Differential pressure meters of the DIR type with two tube springs are used for simultaneously measuring two different pressures, with direct indication of the differential pressure Δp. They consist of two tube spring systems that work independently of one another. Each system has its own pressure connection, labelled with + and -. Both types of pressure are transmitted to a double meter with concentric needle shafts. The pressure are indicated via a scale dial and an indicator.
