BURKERT Fluid Control Systems has launched a new range of mass flow controllers and meters for a wide range of gases applications.
The new range incorporates the manufacturer’s pulsewidth modulated solenoid valves and a new sensor technology, CMOSens. They are available for a wide range of gases, including ammonia.
Gas flows from as low as 20mL/min up to a maximum of 1500L/min can be measured. For the low flows, the units use a bypass measurement system incorporating CMOSens technology.
This technology involves measurement in a specially-formed flow channel containing a silicon chip with an etched diaphragm. Higher flow units use main stream measurement, ensuring fast response times of less than 500ms.
Standard features include: no flow conditioning, sensor diagnostics, automatic auto-tune function for optimal control and high accuracy, and maximum flow diagnostics.
The new mass flow controllers are of modular construction, which enables a system to be readily tailored to meet a customer’s specific requirements. This is consistent with Burkert’s philosophy of customised fluid control systems.
These units have a wide range of applications in heat treatment, plasma surface technology, thermal spraying, gas cutting, foodstuff packaging, and the rapidly-emerging technology of hydrogen fuel cells.
