Series WMH Multi-Jet Hot Water Meter
High Temperature Threshold, Pulsed Output
The Series WMH High Temperature Multi-Jet Water Meters are a series of mechanical, water totalizing meters that display the total water usage in gallons with m3 options. They are available in a range of body sizes and include NPT or BSPT optional couplings. The high temperature resistant brass body is compatible in applications with high temperature water no suitable with standard brass water meters and maintains its accuracy.
Product Applications
- HVAC applications
- Measuring total condenser water flow in residential, commercial and industrial applications
- Remote hot water monitoring
Starting at $172.85

Questions
- 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.
