The digital liquid flow meter accurately & reliably determines liquid flow. It is designed primarily as a flow meter for HPLC systems. Our liquid flow meter has the following features:
The total unit now is very light weight.
The instrument measures liquid flow over a wide range, from 50µl/min to 25 ml/min. You can see the working flow ranges & accuracy in the table below. Flow rate is measured by volume & is independent of the liquid type upto 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) & data can be conveniently output via the build-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
The RS232 output allows the flowmeter to output data to any device fitted with 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. 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 reading. X-on / x-off handshaking is used.
All instruments are supplied with the following :
Specification for HPLC Liquid Flow Meter :
Model | Calibration Point | Calibration at |
LFM-02 | Three | 0.5, 1.0, 2.0 ml/min |
LFM-03 | Four | 0.5, 1.0, 2.0, 3.0 ml/min. |
A Digital Liquid Flow Meter is an electronic device designed to measure the flow rate of liquid substances accurately. It utilizes digital technology to provide precise measurements and often includes features such as a digital display for easy reading of measurements and various electronic components for signal processing and data transmission.
The basic principle behind the operation of a digital liquid flow meter involves the measurement of the volume of liquid passing through a specific point in a given period. This is typically achieved through sensors, such as turbine, electromagnetic, ultrasonic, or mass flow sensors, which detect the movement of the liquid and convert it into electrical signals. These signals are then processed digitally to calculate the flow rate based on factors such as fluid velocity, density, and temperature. We can provide immediate solution in Dhaka.
Digital liquid flow meters offer several advantages over traditional analog meters, including higher accuracy, better reliability, and the ability to provide real-time data for monitoring and control purposes.They are commonly used in various industrial applications, including chemical processing, pharmaceuticals, food and beverage production, water and wastewater management, and oil and gas refining, where precise measurement of liquid flow is crucial for operational efficiency and quality control.
