Microfluidic Flow Meter

LC-M Series Micro flow meter is a kind of positive displacement flow meter, it can detect ultra mini liquid flow as low as 0.5 ml/min, but can still keep accuracy as high as 0.5%F.S, It is a kind of micro PD flow meter for precise flow measurement of mini or low flow liquid, the liquid include water, diesel, fuel, lubricant, petrol, oil, chemical, sealant, toluene, glue, detergents, grease, electrolyte, ethylene, additive, syrup, acryiat-composite., etc . It is widely used in hydraulic system, lubricating industry and painting industries for fluids low-flow rate measurement.

Principle of LC-M Micro flow meter

There is a pair of gears meshing with each other as rotors in the cavity of the micro flowmeter, and the two gears and the chamber respectively form a fixed volume. Liquid flow is measured by calculating the number of flow through the standard volume within a certain period of time. it is a kind PD flowmeter for micro liquid flow measurement.

Install information about ml/min liquid flow meter

Before installation, please read this part carefully, and make sure you really understand the meaning.
1. Before connecting the micro flow meter to the pipeline, be sure to connect the circuit to test whether the signal matches properly (the gear can be rotated by hand or by blowing the flowmeter through the mouth to check the pulse signal)
2. See the wiring diagram of the circuit (see Figure 1).
3. Before the flowmeter is connected to the pipeline, it is necessary to ensure that the pipeline is clean. It is better l to wash the pipeline first. It is recommended to install a filter of 200 mesh or more in front of the flow meter.
4. When connecting the flowmeter with a connector or adaptor, be careful that the PTFE tape or threaded glue should not be over-headed, otherwise it may cause the PTFE tape into the flowmeter to get the flowmeter clogged(see figure 2) .
5. Installation direction requirements (see Figure 3)
