HPLC Liquid Flow Meter
- The ideal instrument for IQ/OQ/PQ and troubleshooting
- Accurate to 1% of reading with guaranteed linearity from 0.05 to 25.00 ml/min
- Durable and easy to use with any HPLC pump
- Easy diagnosis of leaking piston seals or malfunctioning check valves
- Automatic Data Transfer
- Dramatically simplify liquid flow rate data collection for HPLC IQ/OQ/PQ
- Collect flow rate data via RS232 or with a new optional battery powered mini printer
We are very excited about our newly designed flow meter for HPLC. These liquid flow meters have improved performance and a dramatic reduction in size and weight - one third the size and weight of the previous models
The FlowCal 5000 digital liquid flow meter accurately and reliably determines liquid flow. It is designed primarily as a flow meter for HPLC systems used at the end of a flow system where measured liquid is collected. Our latest liquid flow meter has the following improvements:
- New PEEK valve which is fitted with a soft elastomer seal and teflon diaphragm.
- The newly designed sensor head is more stable.
- The user replaceable inlet pipe - is made with a 1/16 inch diameter PEEK tube.
- New modern looking and light weight brushed aluminum case – the total unit now weighs only 12 ounces.
The new instrument measures liquid flow over a wide range, from 50µl/min to 25ml/min. You can see the working flow ranges and accuracy in the table below. Flow rate is measured by volume and is 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 can be conveniently output via the built-in RS232 interface to the full 6-digit reading. No user calibration is required; the unit is generally 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. There are no wetted metallic parts.
