Is There a Cheap Alternative for Flowmeters?

There might be a cheaper way to measure the volume stream: Control valves like the Vary-P by Bronkhorst for controlling high-pressure gas flow with high pressure differences of up to 400 bar (later on extended to 700 bar!) can be used as a more compact and cheaper alternative to flow meters, which are combined with valves that are controlled pneumatically or using a servomotor. For controlling process pressure, Vary-P valves are often combined with pressure meters.

No Time to Waste: Europe's Chlorine Industry and the Mercury Challenge

Time runs out for mercury cell technology in chlorine production, and alternatives are in high demand—Although the December 2017 deadline for the prohibition of mercury cell technology in the EU still seems to be quite far away, time is running out for chlorine producers who have yet to start the conversion or closure process. Even though the regulatory pressures hit a struggling industry hard, it is important to start investigating cost-effective solutions.
