Dwyer Series WMT2 Multi-Jet Water Meter with Pulsed Output

Product Description

Economical, Brass Body, Dry Dial

The Series WMT2 Multi-Jet Water Meter is ideal for commercial and industrial applications. The multi-jet design allows simplicity and accuracy with wide flow ranges even in low flow applications. The meter is designed for long service life and relatively maintenance-free operation, even under adverse conditions. The magnetically driven, hermetically sealed register will not leak or fog and is completely separated from the water. The reed switch is activated by a magnet on the dial, which is directly proportional to the flow rate. The output is perfect for remote monitoring of flow rate or flow totalization, and can interface with PLC’s, counters, data loggers, and SCADA systems.

Not for potable water use, brass contains lead in excess of low lead limits.

FAQ

Question

I recently purchased an WM2-A-C-01,
For my application the pipe is vertical with the water flowing downward. The instructions mention that it should be mounted horizontally. Is it ok to mount vertically?

Answer

Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller. The impeller rotation speed depends on the velocity of the water flow.
If your water is flowing downward it will not rotate the impeller as it does in a horizontal pipe or in a up flow condition. Therefore, you cannot install this instrument in a vertical down flow application and receive accurate readings.
