Liquid Flowmeter
This liquid flowmeters accurately and reliably determine liquid flow. It’s designed for use primarily on HPLC systems at the end of a flow system where measured liquid is collected or dispensed to a drain.
- PEEK bodied valve fitted with soft elastomer seal and PTFE diaphragm.
- Stable Sensor.
- Light weight brushed finish all aluminum case – weight only 320gm.
No user calibration is required.
The unit is normally supplied gravimetrically calibrated at 1.0 (+-10%) ml/min. Calibration at multiple points is available.
All wetted parts are made of PTFE , PEEK , DAI-EL PERFLOUR or Pyrex glass – no wetted metallic parts.
This instrument measures over a range of 50µl /min to 25ml/min, the range and
accuracies are given in the table below.
Flow rates are measured volumetrically and are independent of the liquid type up to a viscosity of 10 centipoise. The unit uses a single chip micro-controller, the flow-rate (rounded to four digits) is displayed on a large four digit back-lit Liquid Crystal display (LCD) and data is output via the built-in RS232 interface to the full 6-digit reading.
