Features
• Can be used as a standard Deadweight Tester.
• Accuracy better than 0.020% of reading, plus the balance error. (The differential pressure between balance piston and measuring piston at the specific line pressure).
• Differential range can differ from the line pressure i.e. line 1000 psi differential range 0 to 200 in H2O.
Two deadweight tester systems are built into a sinlge instrument with a cross connecting valve. The two systems are pressureised in parallel with the cross-connecting valve open, until both pistons and weights are floating at the specific line pressure. With the cross-connecting valve closed the differential pressure is generated by each additional weight loaded to the measuring piston. The balance piston remains floating, ensuring that the line pressure is maintained.
Note: All the models are available in other pressure units.
For kgf/cm² denote Model/2
For kPa denote Model/4
