How does a deadweight tester work
WebDeadweight testers define pressure based on a couple of assumptions. The two big ones are: 1. Piston cylinder temperature 2. Local gravity The pressure value determined by a deadweight tester is the result of summing the pressure values assigned to the loaded weights. Typically the weights will have a value stamped or engraved on them. WebJul 23, 2016 · How does a Deadweight Tester Work?
