Electromagnetic Flowmeters: Are the perfect choice where the metered water contains suspended particles which would prevent other water meters with rotating internals from operating satisfactorily. This type of flowmeter can even be used for handling slurries or water with significant solids content. Accuracy is as good as that offered by turbine flowmeters whilst the operating flow range is greater ( 20:1 or better). The price is higher than mechanical water meters or turbines but the added bonus of no internal moving parts often makes the ‘mag’ meter the water flowmeter of choice for clean or dirty water duties. Whilst operating constraints may push other flow technologies such as Coriolis mass, vortex shedding and positive displacement flowmeters to the fore it is not so common in the task of water measurement. I assume that the quarterly charge is fixed, that is, it doesn't vary as per the volume of water delivered.Water is probably the easiest of all liquids to meter and consequently many flow technologies are available to accomplish the task. Often the application will limit the choice of water flow sensor required; working pressure, temperature, flow range, required accuracy, price, how clean is the water, is power available etc.

They are a screw in type and the size refers to the aperture of the meter inlet - they are volumetric meters and that's the size of the "piston". A QN15 meter will have more than enough of a flow rate. This is most likely what they'll install:
