Liquid FlowmeterLiquid_Flowmeter_Interchim_0316

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.
