Flowmeters for low liquid flow rates

Bronkhorst High-Tech has released an option for its Liqui-Flow Series mass meters and controllers for low flow rates. The instruments are available in compact, rugged designs that are IP65 and ATEX approved for use in Category 3, Zone 2 hazardous areas. The products cover flow rates from 0.25 g/h to 1 kg/h and can be used in applications with pipeline pressures up to 100 bar (1500 psi).

Bronkhorst High-Tech has released an option for its Liqui-Flow Series mass meters and controllers for low flow rates. The instruments are available in compact, rugged designs that are IP65 and ATEX approved for use in Category 3, Zone 2 hazardous areas. The products cover flow rates from 0.25 g/h to 1 kg/h and can be used in applications with pipeline pressures up to 100 bar (1500 psi). The stainless steel sensor has negligible internal volume and no moving parts. Calibration can be performed for virtually every liquid and up to eight calibration curves can be stored onboard the instrument. The digital instruments feature fast response (& 2 seconds) and high accuracy (1% FS or better). Liqui-Flow instruments have analog I/O-signals and an RS-232 connection. The basic PC-board incorporates PID control and alarm and diagnostic functions. www.bronkhorst.com Bronkhorst High-Tech
