Our Plasson meter mounts, boxes and kits come available in various sizes and are priced accordingly. The standard Plasson meter mounts and kits come in sizes from 15mm to 25mm. Several other options are available; for example, the Plasson meter mount kit 3517 comes in two variants of copper adaptors at 25mm x 15mm and 25mm x 22mm. We also sell the widely-used Plasson concentric and water jet water meters. All our water meters in UK are made from the finest and most durable materials at the most affordable prices. https://www.bes.co.uk/elster-v210-manifold-cold-water-meter-20887/?ref=gs&gclid=Cj0KCQjw9b_4BRCMARIsADMUIyrPhohVX2wW1nmtA8L3ftTB-hIIvB6-AJQoX2eg2uiJ_KpB-Ib0IDIaAreuEALw_wcB

I assume that the quarterly charge is fixed, that is, it doesn't vary as per the volume of water delivered. Variable Area Flowmeters: A simple ‘float in a tube’. Probably the least expensive and least accurate of all water flow meters but eminently suitable where a visual indication of flow is all that is required. Care must be taken with regard to not exceeding working pressure and temperature limits … particularly in the case of plastic tube units. V/A flowmeters are available for flows as low as 1 cc/min up to 1000 l/min with accuracy 2-3 percent at best. Getting ready to start on my home build, and have two options for water supply from the council, and was looking for guidance as to what I am better getting.

Other factors obviously also come into play such as the run distance Vs friction loss consideration plus the tank's location given that the land is on a slope. 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.

Don't mind too much the extra cost for connection, but the quaterly charge for the 25mm is 1.5625 times the 20mm. Re the pump, if it is submersible, have it raised off the floor or placed in a shallow container to prevent it from vacuuming the tank's floor.

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. 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. The meter size is different from the pipe size. 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: Turbine Flowmeters: Can be used in cases of higher working pressures up to 30000 psig, where higher accuracy is required, or hygienic approval is mandatory. Turbines don’t have the rangeability of mechanical water flowmeters, usually operating over a 10: turndown, but offer far higher accuracies in the region of 0.2 to 0.5%. They can also be coupled with secondary instrumentation to indicate flow rate and total as well as provide a current and/or pulse output.
