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.

Three modes of operation are available:
• Printer Mode: liquid flow readings are displayed on the LCD and output to a printer if one is connected. A running average option is available in this mode
• Terminal Mode: in this mode the liquid flowmeter is controlled by the terminal or PC. Extra commands for averaging any number of readings are included.
• Test Mode: this mode allows the user to test the display, valve and RS232 interface and also display the calibration date.

The RS232 output allows the flowmeter to output data to any device fitted with an RS232 serial interface e.g. printer, terminal or personal computer. The unit is supplied with an RS232 cable fitted with a nine way female plug to connect directly to the COM port of a PC. By using the Terminal or Hyper-Terminal program supplied with MS Windows results can be collected and displayed or pasted into Excel or other programs to produce graphs or statistical analysis. The baud rate is internally switch selectable for 19200, 9600, 4800, 2400, 1200, 600, 300 baud with the option of sending a CR/LF after each reading. X-on / X-off handshaking is used.

All instruments are supplied with the following:
• Mains ‘wall block’ power supply with a choice of 240v 3 pin UK, 230v 2 pin European or 100v 2 pin USA/Japan.
• RS232 input/output cable: 8way mini-din plug to PC COM port 9 pin female.
• UKAS traceable single point flow calibration certificate is supplied as standard (UKAS is the UK equivalent of NIST)
• Universal mounting kit: allows free standing mount, wall mounting, ‘stack system’ mounting and bottle top mount.
• Black plastic carrying case with foam inserts. All parts of the mounting kit are packed within the carrying case.
• Cleaning kit now supplied with the flow meter.
