HPLC flow mete

HPLC 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 aluminium case – weight only 500gm.

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 50ml/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.
