LC-MPN Series Flow meter with wetted parts made of PP or PVDF for corrosive liquid measurement, capable of detecting a minimum flow rate of 13 ml/min.LC-MPN Series Flow meter can be used for sulfuric acid flow meters, hydrochloric acid flow meters, nitric acid flow meters, and hypochlorous acid flow meters

Operating Principle

when the corrosive liquid enters through the inlet of small flow sensor , it flows onto the sensor, generating a signal proportional to the flow rate. The magnetic sensor detects the number of rotations within the chamber and outputs a square wave pulse signal. The mini flow meter for acids features a simple structure, high durability, stable operation in low flow conditions, and excellent repeatability.

Application 1: Batch Control with low flow Flow Meters for Tap Water and Upper Water

Low flow flow meters, when used with solenoid valves, PLCs, or batch controllers, enable precise quantitative control of tap water and upper water. The flow meter continuously measures the low flow flow rate, sending data to the controller, which regulates the solenoid valve to ensure accurate water dispensing. Once the preset volume is reached, the system automatically stops the flow, ensuring consistency.
This solution is ideal for industries requiring precise water dosing, such as food production, laboratories, and pharmaceuticals. The compact size and high accuracy of micro flow meters make them suitable for low-flow flow measurement applications, enhancing efficiency and reducing waste.

Application 2: Proportional Infusion of Synovial Fluid with Micro Flow Meters

Proportional Infusion of Synovial Fluid with low flow Flow Meters
