If you're going to wholesale high quality Portable Mechanical Water Flow Meter – Brass Single-Jet Design, welcome to get pricelist and quotation from our factory.
Precision flow measurement in a portable package. This portable mechanical water flow meter – brass single-jet design delivers accurate readings via tangential impeller drive, with pulse output for remote monitoring. Built for residential and light industrial use. Reliable. Durable. Ready to work.
Products Description
The portable mechanical water flow meter – brass single-jet design operates on the rotor-type principle. Water enters tangentially through the case inlet, driving the impeller to rotate, while a gear reduction mechanism continuously records revolutions to track the cumulative volume passing through the meter.
Conforming to ISO 4064 Class B accuracy standards, this mechanical water flow meter is suitable for residential billing, commercial buildings, and light industrial process control. Available in DN15–DN25 sizes with BSP or NPT thread options.

Working Principle
This kind of mechanical water flow meter utilizes a portable brass single-jet mechanism with a rotor type of operation. Water flow in the water flow meter enters tangentially through the inlet in its casing and drives the impeller to rotate. A gear reduction mechanism records the number of rotations of the impeller, keeping track of the total amount of water that flows through the water flow meter.

Application & Selection Guide
How to Choose the Right Mechanical Water Flow Meter?
When selecting a mechanical water flow meter for your project, consider the following key factors:
| Factor | Consideration |
| Pipe Size | Match the meter size (DN15, DN20, or DN25) to your pipeline diameter and expected flow rates. |
| Water Temperature | Confirm whether the application requires cold water (≤30°C) or hot water (≤90°C). |
| Output Signal | If remote reading or BMS integration is needed, select a model with reed switch pulse output. |
| Water Quality | This single-jet design is best suited for clean water with low impurities. For abrasive or dirty water, please contact us for alternative recommendations. |
| Connection Type | Choose between BSP or NPT threads based on your local piping standards. |
| Custom Requirements | Different lengths, non-return valves, and plastic body options are available on request. |
