Gems Sensors and Controls
As liquid passes through the unit’s body, a magnetic rotor spins at a rate proportional to the flow rate. The magnetic fields turning with the rotor excite a static Hall Effect sensor located in the body and generate a series of voltage pulses. Digital rate meters, totalizers, and other electronic controllers then use the output signal.
The RotorFlow sensors are available in port sizes of 0.25 to 1 in. and monitor fluids with flow rates ranging from 0.1 to 60 GPM. The units are appropriate for applications such as water purification, dispensing systems, chemical metering, and chillers and heat exchangers.
The unit’s dedicated fan creates an inflow of more than 0.5 m/s. The inflow speed and laminar flow can be adjusted to different set points if required. The inflow and the device’s multistage filtration help shield operators from hazardous materials. Testing has shown that the CytoUltra device protects operators from 20-nm particles. The cabinet is appropriate for pharmaceutical manufacturing processes.
