Thermal Non-Invasive Low-Flow Flowmeters, 50 to 1500 nL/min

Nano-and micro-flow measurements for precision laboratory applications

Resolutions down to 500 pL/min

Response time < 50 ms

These liquid mass flowmeters enable extremely fast and accurate measurements of ultra-low liquid mass flows, and operate with total media isolation, very little dead volume, and no moving parts. The flowmeter detects liquid mass flow by measuring heat transfer through the tubing material of a glass capillary. On a microchip outside the capillary, a heating resistor on a thermally optimized membrane is kept above ambient temperature. In the presence of liquid flow inside the capillary, the temperature distribution upstream and downstream is disturbed—this difference is then measured. CMOSens^®sensor technology combines a high-precision thermal sensor element with digital signal processing on one single CMOS chip. In addition, the digital intelligence of the CMOSens sensor technology enables digital interfaces that permit an easy link with PCs, PLC, and other controllers.

All measurement data is fully calibrated and temperature compensated by means of an internal microcontroller. Excellent chemical resistance and bio-compatibility are ensured, and the process medium only gets in contact with the straight sensor capillary. Typical applications for this sensor include precise liquid mass flow and volume measurement for analytical instruments, medical devices, and process control. . Models 32611-00 to -08 are calibrated for water only. Superior repeatability of the measurement signal is still maintained for other media and thus allows after-measurement-correction on a computer or microcontroller. Model 32611-10 is calibrated for IPA only but can also be used for repeatable measurements of other hydrocarbons such as ethanol, acetone, diesel, petroleum, ether, and most other media; however it does not work with aqueous solutions.
