Mercury Free Piston Prover Technology

Previous generations of piston provers utilized mercury, a known hazardous fluid, as a low friction seal to allow zero gas leakage past the piston. These piston provers were designed in a time when mercury was considered less dangerous. Many healthcare and manufacturing facilities have removed mercury containing products as well as introduced non-mercury containing alternatives.…

Bios DryCal Technology VS Other Gas Flow Calibration Technology

DryCal technology was created by Bios because there was a need in the market place to eliminate messy soap bubble meters which did not ensure accuracy or traceability of their measurements. Bios patented DryCal® technology which uses a nearly-frictionless graphite composite piston housed within a flow measuring cell of precisely quantified dimensions. Bios originally designed our…
