Types of Multi-Jet Water Meter

 

The multi-jet water meters produced by our company mainly include the following types

Volumetric Dry Type Brass Body Water Meter

Multi-Jet Dry Type Brass Body Cold Water Meter

All the materials of the multi jet water meter selected by resistance to corrosion. The conception of the Magnetic Protection to against the external influences.

Multi-Jet Liquid Filled Type Brass Body Cold Water Meter

Multi-Jet Liquid Filled Type Brass Body Cold Water Meter

Sizes from Dn15 to Dn50 designed and manufactured by NWM and meets the requirements of Directive 2004/22/EC on measuring instruments.

Multi-Jet Dry Type R160 Cold Water Meter

AWWA NSF Multi-Jet Dry Type Plastic Water Meter

Water flows through the meter's strainer (inlet and internal) and into the measuring chamber where it drives the impeller. A driving magnet transmits the movement of the impeller to a driven magnet located within the sealed register.

 

Features of Multi-Jet Water Meter

 

Our multi-jet water meters are available on various pulse output options. Thus, they have become an excellent choice for water flow monitoring in commercial, industrial, domestic, and batch control applications.


These meters have multiple ports surrounding the impeller to create multiple jets of water, wherein their rotational speed depends on the water flow velocity.


While our multi-jet meters accurately measure and display the water level at low flow rates, they also help control the speed and velocity of the inside fluid.


We engineer these meters using high-quality materials. Thus, they can withstand electrical conductivity, harsh industrial environments, high pressures, and temperatures.


Our meters have a long operational life and minimal maintenance cost. Thanks to low RPM turbines and high-quality construction materials.

 

Our multi-jet meter has an internal strainer, which protects the magnetic drive against any interfaces from external fields. 

 

 
Applications of Multi-Jet Water Meter
 
01/

Residential Water Metering: Multi Jet Meters are often used to measure the water consumption of individual homes and apartments.

02/

Commercial Water Metering: Multi Jet Meters are also used in commercial applications to measure the water consumption of buildings and facilities.

03/

Irrigation: Multi Jet Meters can be used to measure the water consumption of irrigation systems, allowing for more efficient use of water.

04/

Industrial Applications: Multi Jet Meters can be used in industrial applications to measure the flow rate of water in manufacturing processes.

 

Installation Steps of Multi-jet Water Meter

 

Horizontal Installation

Ensure the meter is installed horizontally with the counter facing upward. Verify that the installation is level.

Attach Tailpieces

Fit the separately supplied tailpieces to the water meter using the provided sealing washers.

Apply Thread Sealing Tape

Wrap P.T.F.E. thread sealing tape around the male threads of the tailpiece linings.

Attach Pipe Adaptors

Screw appropriate female pipe adaptors onto the male end of the tailpiece lining. Note: Avoid overtightening, as this can cause leaks. The sealing tape creates the waterproof seal, not the tightness of the fitting.

Positioning the Meter

Choose a location where the water meter will always be full of water. Do not install it at the discharge end of a pipe.

Check Flow Direction

An arrow on the meter body indicates the correct flow direction. Install the meter in line with this arrow to ensure correct flow. The built-in non-return valve will prevent flow if installed in reverse.

Install Shutoff Valve

Place a shutoff valve in the pipeline upstream of the meter for convenient future maintenance.

Connect and Secure Fittings

Fit the meter by connecting the pipe to the adaptors and tightening the fittings securely.

Charge the Lines Gradually

When turning the water on, do so gradually to allow all air to escape before fully opening the valve. Subjecting the meter to high-velocity air can cause irreversible damage.

 

Optimal Storage Conditions For Multi-Jet Water Meters

 

 

Temperature control is a key aspect of storing multi jet water meters. It is recommended to store these meters in a controlled environment with a stable temperature range. Extreme temperature fluctuations can adversely affect the performance and accuracy of the meters. High temperatures can cause components to expand or degrade, while low temperatures can lead to mechanical issues. Maintaining a moderate and consistent temperature helps preserve the meter's functionality and accuracy.


Moisture control is another critical consideration for storing multi jet water meters. Exposure to excessive moisture can lead to corrosion, electrical issues, and damage to sensitive components. It is essential to store the meters in a dry environment to prevent moisture-related problems. Implementing measures such as using desiccant packs or dehumidifiers can help maintain optimal humidity levels and protect the meters from moisture damage.

FAQ

Q: How does a multi-jet water meter work?

A: Unlike single-jet meters, which have one port, multi-jet meters have multiple ports that surround an internal chamber to create a flow of water against the turbine. Because the load is evenly placed across the impeller, multi-jet meters retain accuracy even a lower flow rates and give a much longer life.

Q: What is the odometer on a water meter?

A: A water meter's register, like a car odometer, displays the total water usage in a cumulative manner. It typically reads from left to right, with each digit representing a different unit of water usage (e.g., cubic feet, gallons). The numbers on the register keep a running total of all the water that has passed through the meter since it was installed.

Q: What are the main components of a multi - jet water meter?

A: It mainly consists of a casing, an impeller measuring mechanism, a reduction mechanism, and an indicator. Some water meters may also be equipped with accessories such as a reed switch and a non - return valve.

Q: How does the structure of a multi - jet water meter differ from that of a single - jet water meter?

A: A multi - jet water meter has multiple ports surrounding the internal chamber to create a water flow that acts on the turbine. In contrast, a single - jet water meter has only one port that generates a jet of water to directly impact the impeller.

Q: What is the measurement range of multi - jet water meters?

A: The nominal diameters of multi - jet water meters are usually in the range of 15 - 500 mm, and the flow rate range is wide, which can meet the water measurement needs of different users, from residential to industrial use.

Q: What should be paid attention to when replacing parts of multi - jet water meters?

A: When replacing parts, it is necessary to ensure that the replaced parts are of the correct model and specification. Follow the assembly sequence and requirements during installation to ensure proper installation of the parts. For example, when assembling the impeller and the sealing counter, pay attention to the installation position and direction.
