Installation Instructions

The Infinity EVO Woltmann Water Meter is designed for reliable installation in horizontal or vertical (upward) positions, depending on the application and site setup. Its integrated flow straightener and U0-D0 design allow installation without the long straight pipe runs typically required for bulk meters. Always ensure the pipeline is flushed before installation and that the meter is installed in the correct flow direction.

The Infinity EVO Class B water meter is approved by the NRCS for horizontal installation only. It must not be installed vertically or on its side.

We strongly recommend installing an inline strainer upstream of the meter to prevent clogs and potential damage from debris such as sticks and stones. Note: Strainers are sold separately.

Ensure that the meter is installed with a straight length of pipe free of valves, bends, or fittings equal to 10 times the diameter of the meter upstream and 5 times the diameter downstream.

Note: This meter is designed for cold water with a maximum operating temperature of 50°C. Exceeding this temperature can cause irreversible damage. Avoid soldering or applying heat near the meter during installation, as heat can travel through the pipe and damage the meter's internals.

Prevent installation in areas subject to vibration, shock, cavitation, water hammer, or rapid valve operations, as these conditions can affect meter accuracy and cause damage.

Ensure that the 2 pipe sections at the metering point align correctly and that there is no excessive mechanical stress on the meter body, as improper installation can cause irreparable damage.

To prevent freezing, install the meter at least one meter away from potential freezing points, such as standpipes, to avoid water freezing and potentially bursting the meter.

  1. Horizontal Installation: The meter must be installed horizontally with the counter positioned on top. Ensure the installation is level.
  2. Water Level: Position the meter where it will remain fully submerged in water. Avoid placing the meter at the discharge end of a pipeline.
  3. Flow Direction: The meter features a flow direction arrow cast into its body. Ensure the meter is installed in the correct direction according to the pipeline flow.
  4. Isolation Valves: It is advisable to install isolation valves both upstream and downstream of the meter for backflow prevention and ease of maintenance.
  1. Flush the Line: Thoroughly flush the service line upstream of the meter to remove any dirt and debris.
  2. Clean Flanges: If replacing an old meter, clean the existing flange faces with a wire brush and remove any old gasket material.
  3. Install Bolts: Insert bolts through the meter flange holes with the heads facing the meter side and the threads extending towards the pipeline.
  4. Position Gasket: Place the gasket between the bolts and align the meter flange with the pipeline flange, ensuring the gasket is centered. Do not reuse old gaskets or use multiple gaskets, as this may cause leaks.
  5. Tighten Bolts: Lubricate the bolts and tighten the nuts starting with the topmost ones. Initially, tighten them by hand and ensure the gasket is properly positioned.
    Final Tightening: Once all nuts are hand-tight, tighten them in the specified order using a ring spanner of the correct size (see Diagram 1).

FAQ

A Woltmann water meter is a type of bulk water meter designed for larger pipe sizes and higher flow applications. It is commonly used in commercial, industrial, and municipal systems where durable construction, reliable accuracy, and long-term performance are important.

The meter size is clearly marked on the body of the unit. You can also refer to the product specification sheet or use the flow rate table to confirm the correct size for your application.

Yes. Using a meter that is too large may under-register low flow rates, while a meter that is too small can cause pressure drops and increase wear on internal components.

This Infinity EVO model is available in 150mm and 200mm sizes. The pipeline size should match the selected meter size to ensure accurate measurement and reliable system performance.

The Infinity EVO Woltmann Water Meter is designed for flexible installation and does not require upstream or downstream straight pipe sections (U0-D0). This means you can install it without needing long straight runs before or after the meter.

“m³” stands for cubic meters, which is the unit used to measure water volume. One cubic meter equals 1,000 litres.

The meter is rated for cold potable water up to 50°C and can handle a nominal working pressure of 1600 kPa (16 Bar).

Yes, the Infinity EVO Woltmann Water Meter can be installed in both horizontal and vertical (upward) positions without affecting performance.
