Monument Water Flow Weir Gauge - 1515U

The Monument 1515U is used to measure water flow rates accurately, which is essential for installing plumbing fixtures and diagnosing issues with water systems, such as boiler efficiency.

It measures flow rates from 2 to 25 litres per minute (LPM) and also displays the equivalent in gallons per minute (GPM) from 1 to 5 GPM.

The strainer helps to reduce water turbulence, ensuring a more accurate and stable reading on the gauge.

No, this gauge measures flow rate (volume of water per unit time), not static water pressure. For pressure, a separate pressure gauge is required.

If the flow rate measured at a hot water outlet is significantly lower than the boiler's recommended output, it may indicate scale buildup is restricting flow.

Yes, it can be used to measure the flow rate of both hot and cold water, provided the water temperature is within the operating limits of the plastic construction.

Regular cleaning of the mesh strainer and ensuring the unit is stored correctly are the primary maintenance requirements.

Ensure the gauge is securely connected to the outlet. Check if the water supply valve is fully open. Verify that the flow rate is within the gauge's 2-25 LPM range. Inspect the mesh strainer for blockages and clean if necessary.

Ensure there are no air locks in the connected pipework. Make sure the gauge is installed in a straight run of pipe after the connection point, if possible, to minimize turbulence. Check that the mesh strainer is clean and properly fitted.

Ensure you are using the correct adapter if needed (not included). Check for any damage or debris on the outlet threads or the gauge's connection point.
