The IFLO Single Jet Water Meter is a mechanical water meter designed to measure the total volume of tap water flowing through closed pipes. It uses a single-jet measuring principle combined with a dry dial and magnetic transmission structure, providing a straightforward way to measure accumulated water consumption.
According to the catalog, the water meter is available for both cold water from 0.1–50°C and hot water from 0.1–90°C, with a pressure rating of 1.6 MPa. The meter features a brass body, brass cover, and brass fittings.
The catalog also identifies several key characteristics, including antimagnetic and antifreezing construction, ISO 4064 Class B, and an optional pulse line that can be connected to LoRa or LoRaWAN systems.
IFLO Single Jet Water Meter for Total Water Measurement
The IFLO Single Jet Water Meter is designed for applications where the required measurement is the total volume of water passing through a closed pipeline. It is therefore intended to record accumulated water consumption rather than simply indicate whether water is flowing.
The meter uses a single-jet construction. Water entering the meter interacts with the internal measuring mechanism, and the resulting mechanical movement is transferred to the indicator through a magnetic transmission system. The catalog specifically identifies the product as a single-jet water meter with a dry dial and magnetic transmission structure.
The dry dial keeps the reading mechanism separated from direct contact with the measured water. The magnetic transmission structure transfers the measuring movement to the display, allowing the accumulated water volume to be read from the dial.
This design makes the meter suitable for conventional water metering applications where a mechanical meter is required for measuring the total volume of tap water flowing through closed pipes.
For ValveLink customers, the IFLO Single Jet Water Meter provides a compact solution for water consumption measurement in systems using the available threaded connections and nominal sizes.
Single Jet Water Meter Construction and Materials
The IFLO Single Jet Water Meter uses a brass meter body, while the catalog specifies a brass cover and brass fitting.
The main construction features listed in the catalog are:
- Single-jet measuring structure
- Dry dial
- Magnetic transmission structure
- Antimagnetic construction
- Antifreezing construction
- Brass meter body
- Brass cover
- Brass fittings
The combination of a single-jet measuring structure and magnetic transmission provides a mechanical measurement arrangement in which the measuring mechanism drives the dry indicator.
The catalog also identifies the meter with ISO 4064, Class B and lists MID, CE, ISO 9001, ISO 14001, and ISO 45001 markings/certifications.
The product should be selected according to the actual application requirements, including water temperature, operating pressure, nominal pipe size, and connection dimensions.
Technical Specifications of IFLO Single Jet Water Meter
The catalog specifies the main working conditions and technical characteristics of the IFLO Single Jet Water Meter. For cold water, the specified temperature range is 0.1–50°C. For hot water, the range is 0.1–90°C. The specified pressure is 1.6 MPa.
| Parameter | Specification |
|---|---|
| Product type | Single-jet water meter |
| Measuring purpose | Total volume of tap water |
| Meter body | Brass |
| Cover | Brass |
| Fitting | Brass |
| Cold water | 0.1–50°C |
| Hot water | 0.1–90°C |
| Pressure | 1.6 MPa |
| Measuring structure | Single-jet |
| Dial | Dry dial |
| Transmission | Magnetic transmission |
| Protection characteristics | Antimagnetic, antifreezing |
| Standard | ISO 4064, Class B |
| Pulse line | Optional |
| Communication connection | LoRa / LoRaWAN |
The catalog states that the pulse line is optional and can enable connection to LoRa or LoRaWAN.
This option is relevant when the meter needs to be incorporated into a remote water monitoring system. The supplied catalog does not provide further details about the communication protocol or pulse value, so these parameters should be confirmed for the required configuration before ordering.
Size, Threaded Connection and Dimensions
The IFLO Single Jet Water Meter is available in DN15, DN20, and DN25 configurations according to the catalog. Each size is associated with a corresponding threaded connection and physical dimensions.
| Nominal Size | Threaded Connection | Length L1 | Width B | Height H | Weight |
|---|---|---|---|---|---|
| DN15 | G3/4 | 110 mm | 66 mm | 67 mm | 0.4 kg |
| DN20 | G1 | 130 mm | 66 mm | 80 mm | 0.53 kg |
| DN25 | G1 1/4 | 160 mm | 80 mm | 91.5 mm | 0.91 kg |
The catalog provides the dimensional information in millimeters and identifies the threaded connection for each nominal diameter.
When installing the meter into an existing pipeline, the nominal size, thread connection, overall length, width, and height should be checked before ordering. This is especially important when replacing an existing meter because the new meter needs to fit the available installation space.
The available sizes are intended for the corresponding pipeline requirements shown in the catalog. If a different nominal diameter or connection is required, it should be confirmed with ValveLink before placing an order.
Flow Range, Reading Range and Measurement Parameters
The catalog provides Q1, Q2, Q3, and Q4 flow parameters for the different nominal sizes. These values define the flow characteristics associated with the respective water meter configuration.
For example, the catalog data includes the following values:
| Size | Q1 (m³/h) | Q2 (m³/h) | Q3 (m³/h) | Q4 (m³/h) |
|---|---|---|---|---|
| DN15 | 0.03 | 0.05 | 1.5 | 2.5 |
| DN20 | 0.05 | 0.12 | 2.5 | 4 |
| DN25 | 0.07 | 0.28 | 3.5 | 7 |
The meter register provides a maximum reading of 99,999 m³ for the listed sizes. The catalog also provides minimum reading values for the different configurations.
These parameters should be considered when selecting the correct meter size. The nominal diameter alone should not be the only selection criterion; the expected water flow should also be compared with the Q1–Q4 values specified in the catalog.
For ValveLink customers, providing the expected minimum, normal, and maximum flow rate together with the pipe size helps determine whether the selected water meter configuration is appropriate for the application.
Applications and Selection from ValveLink
The IFLO Single Jet Water Meter is specified for measuring the total volume of tap water flowing through closed pipes.
Its DN15, DN20, and DN25 configurations make it suitable for water metering installations where these nominal sizes and threaded connections are required. The available G3/4, G1, and G1 1/4 connections correspond to the three listed meter sizes.
Typical selection considerations include:
- Nominal pipe size: DN15, DN20, or DN25
- Threaded connection: G3/4, G1, or G1 1/4
- Water temperature: 0.1–50°C for cold water or 0.1–90°C for hot water
- Pressure: 1.6 MPa
- Expected flow rate: Check against Q1, Q2, Q3, and Q4
- Installation dimensions: Confirm length, width, and height
- Remote monitoring: Optional pulse line for LoRa or LoRaWAN connection
The optional pulse line is particularly relevant when the water meter needs to provide data to a remote monitoring system. The catalog confirms that the optional pulse line can connect to LoRa or LoRaWAN, while the standard configuration uses the mechanical dry dial for local reading.
When requesting the IFLO Single Jet Water Meter from ValveLink, customers should provide the pipe size, required connection, water temperature, operating pressure, expected flow range, and whether an optional pulse connection is required.
Contact ValveLink for the IFLO Single Jet Water Meter and provide your application details so the appropriate size and configuration can be checked against the catalog specifications before ordering.
