What it is not the answer for
Read this before asking for a price: one of these conditions is what turns a good meter into a bad installation.
- Media that crystallise or solidify on the diaphragm without a flush seal
- Pressure spikes well beyond the stated overload, unless a snubber is fitted
- Sanitary or highly corrosive service without the matching diaphragm material
Maintenance and service life
Check the zero at atmospheric pressure once a year, and replace the wetted seal if the medium crystallises or solidifies. In pump station service, fit a damping or surge-protection device instead of increasing the range: an oversized range hides the surge it was meant to measure.
Applications
Where this model is used
Each application names a measuring point and the conditions that decide the selection.
WW-PS
Pump Station Wet Well Level and Pressure
Wet well level control and rising main pressure for sewage pump stations, where foam and grease blind a non-contact sensor.
WW-WD
Water Distribution District Metering
District metering and pressure management for distribution networks, where night flow and peak demand differ by an order of magnitude.

The same category holds the models that solve the neighbouring problem, and the price difference is usually smaller than the cost of the wrong principle.
