ProSight NPN Pulse Signal Measure Water Flow Food Grade Water Flow Sensor
ProSight NPN Pulse Signal Measure Water Flow Food Grade Water Flow Sensor Inner Diameter 2mm/3.5mm 3.5-24VDC POM is a compact positive displacement flow sensor designed for measuring ultra-low liquid flow rates with high accuracy. It is primarily used in laboratory equipment, precision dispensing systems, chemical dosing, and industrial process control. Featuring miniature 2 mm to 3.5 mm internal diameter connections, pulse signal output, compact construction, and excellent repeatability, it provides stable and reliable flow measurement for demanding applications.
What is the Product?
ProSight NPN Pulse Signal Measure Water Flow Food Grade Water Flow Sensor is a miniature positive displacement flow sensor engineered for precise measurement of very small liquid flow rates. Unlike conventional turbine flow meters, it uses two precision-machined gears that rotate as liquid passes through the measuring chamber. Each gear rotation corresponds to a fixed volume of liquid, allowing highly accurate volumetric flow measurement regardless of changes in viscosity or pressure.
Its miniature design with 2 mm and 3.5 mm internal diameter connections makes it ideal for compact fluid systems where installation space is limited. It is commonly integrated into laboratory instruments, medical analyzers, chemical dosing equipment, fuel systems, lubrication systems, ink dispensing, and precision industrial machinery.
How It Works
The flow meter operates using a positive displacement gear mechanism.
- Liquid enters the measuring chamber.
- The flowing liquid rotates two precision gears.
- Each gear revolution represents a known volume of liquid.
- A magnetic or Hall-effect sensor detects gear rotation.
- The sensor generates pulse signals proportional to the liquid flow.
- The control system converts the pulse frequency into instantaneous flow rate and total accumulated volume.
Why Choose This Product?
The Micro Gear Flow Meter is specifically designed for applications requiring highly accurate measurement of micro-flow liquids. Its positive displacement principle provides excellent repeatability even when measuring viscous fluids or extremely low flow rates.
Compared to traditional flow meters, it offers higher precision, minimal pressure loss, stable performance, and compact dimensions suitable for OEM integration. It requires minimal maintenance and provides reliable long-term operation in automated liquid handling systems.
