Combination of Equilibar valves and Coriolis mass flow measuring for broad flow range and high stability

When it comes to achieving exceptional control and precision in flow measurement and regulation, Equilibar valves and Bronkhorst Coriolis mass flow meters are a winning combination. Taken together, they offer extraordinary capabilities and unparalleled performance. From controlling minute flows of 0.1 to 5 grams per hour at high pressures of 150 bar gauge, to effortlessly adapting for varying media types, Equilibar valves and Bronkhorst Coriolis mass flow meters provide process engineers and scientists with the tools they need to push the boundaries of pressure or fluid control.

An example of 17 custom-built flow controllers is shown on this page: These flow controllers can control 0.1…5 grams per hour at a pressure of 150 bar gauge and with control stability of 0.1%. The maximum pressure for these flow controllers is 200 bar and they can easily be configured to 200 grams per hour of either liquid, gas, or supercritical media. We combined the flow controllers with Equilibar dome-loaded, diaphragm-sealed multiple-orifice valves in stainless steel, which bring a Cv of 10E-9 to 0.01 to the application. For the sensor, we furthermore used Bronkhorst ML120 Coriolis mass flow meters. Making use of the Coriolis measuring principle on the impulse from the process media, enables the detection of a phase change in a vibrating measuring tube – resulting in a direct measure of mass flow under these conditions. At the flow rates mentioned above, we can only conclude that this is an impressive piece of technology, that is worth sharing!
