Choosing the wrong meter will mean that it counts too much water, or too little, or simply doesn't count at all. e6)EIgf"{lf||U7$8GzR'F5'_)F]TH_rGetd|lF hV23dp",5g;p~Y7U?K 
It can be expressed as a ratio, e.g., 10:1; as a range of measurement, e.g., 1-100 GPM; or as a velocity span, e.g., 0.3 FPS to 20 FPS. 0000019163 00000 n
However, for economic reasons, they can be smaller, as long as you bear in mind that this will lead to load losses.

In this case, if you pass a conductive fluid through the meter, where two powered coils produce a magnetic field, you close the circuit and the voltage will be proportional to the speed of the fluid. The low-flow rates are based on an error not greater than 1.5%, typically considered acceptable for these types of meters. 0000009480 00000 n This figure is the meter'sconstantflow rate or Q3.

Water meter counter can be installed inline on the pipeline, in the horizontal or vertical position (h/v) in flats or detached houses. S?. PRM Filtration is one of the nation's leading providers of industrial-grade parts, supplies, and equipment.
0000035294 00000 n Electromagnetic flowmeters work differently and, therefore, they are also sized differently. 0000010848 00000 n 0000021598 00000 n In other words, exceptionally, at this level it can operate and maintain measurement errors below the maximum permissible error values, recovering its functionality when it subsequently returns to normal operating conditions.

Turndown isnt an issue for a flowmeter, assuming it is correctly specified, if flow is steady, e.g., at 250 GPM.
0000008267 00000 n
For our purpose, we will focus our attention on velocity-measurement devices. 0000025713 00000 n 0000017170 00000 n A flowmeter, though not the most expensive water system component, is critical as the means for registering water usage. 0000006226 00000 n A. This "usable turndown" is closer to a nominal 25:1 or 30:1 than to the 100:1 that manufacturers state the meters to be capable of. PRM Filtration has one of the largest rental fleets of remediation equipment and systems in the nation. It is important to note that the tubes must always be full for these meters to measure correctly. But, it didn't transact. Mechanical meters also require extra maintenance. Some are mechanical meters bearing extra components such as filter baskets to trap contaminants. 0000001224 00000 n ", Turndown ratio can be determined by dividing the highest flow by the lowest flow possible. endstream endobj 20 0 obj <>stream With an accuracy of +/-3% of reading, you can count on the meter providing consistent, reliable readings so you have the information you need to manage your liquid flow. PRM carries 3", 4", and 6" flanged Woltmann helix style water meter for industrial use. 0000021505 00000 n
Also remember consider the minimum flow rate(Q1) of the supply network, below which meters are unable to provide accurate readings. With the factory-calibrated battery-operated display, all you need to do to get started is plumb in your pipe and turn on your flow. Water meter comes in two thread sizes: 1/2 or 3/4 Inch. of a foot per second. If the high flow to be measured is 1000 GPM and the low flow to be measured is 10 GPM, the desired turndown is said to be 100:1 or better. The operating flow rates of a water meter are defined as follows: The key to ensuring that the meter works correctly is to make sure that the maximum flow rate passing through the meter never exceeds Q3. 0000002216 00000 n DZ#~KT3\5S`!]cSmL mdMv#3.@\&gf`K{];y[mW-qQf8,67ab6s Visual blade inspections, recalibrations due to wear and cleaning buildup on blades and other parts are among additional expenses to be considered.
