Kent Meters - Specifications
Tamperproof operation
The V100 offers unrivalled resistance to illegal tampering: its unique conical body-half design eliminates the risk of disassembly whilst in service and the mechanically driven cyclometer-type counter is resistan
t to magnetic interference. An optional return reverse flow restrictor provides further protection against outside interference, preventing the meter being operated in the reverse direction to reduce the reading. This restrictor cannot be removed without opening the meter and destroying the seal. Revolutionary grooved piston
Meter stoppages are substantially reduced,durability enhanced and performance
improved as a result of a uniquely-designed grooved piston within the meter measuring chamber, increasing applications flexibility (available in 15mm and 20mm sizes).

Vital management information tool
Valuable management information can be obtained with the aid of a probe pulse unit, available on V100 meters. The unit provides important consumption and flow information on a temporary or permanent basis, allowing examination and analysis of consumption patterns and providing a valuable early detection of leaks. Volt-free probe pulsars provide output signals for interrogation by externally powered reading devices and can be attached to previously installed V100 meters with the facility to install a probe pulse unit, at any time without interrupting the water supply .

V100 Volumetric
The V100 is the world’s favorite domestic. water meter, with over 50 million already in service in over 100 countries, and offers accuracy, long life, low maintenance and tamper proof operation.
Available in sizes from 15mm to 40mm, with flow rates of between 7.5 l/h to 20 m3/h,V100 meters offer unrivaled performance to BS5728, ISO4064 Class C or D (for 15mm to 25mm only). In addition, models can provide valuable management information via a probe pulse unit upgrade. Unrivaled accuracy in any position, for any flow Due to the volumetric rotary piston
measurement principle, the V100 range can achieve the highest levels of reading accuracy
even at the lowest flow rate. The meter can be installed in any position: horizontally, vertically
or inclined pipelines, maintaining optimum performance with no loss of accuracy. Robust, leak-proof construction The use of advanced engineering plastics for the meter’s measuring chamber significantly reduces wear and helps maintain reliable, accurate measurement over all operating conditions. Solid particles are gathered by a large surface area strainer, further preventing damage; and its advanced design ensures that partial obstruction of the strainer will have no ill effect on the accuracy of the meter’s registration. A body ‘O’ ring seal between the measuring chamber and meter body ensures that internal leaks which could by-pass the measuring chamber are eliminated. Easy to read The counter is fully sealed, liquid filled using
a vacuum and offers simple, straight-reading presentation. The number rollers are completely immersed in a lubricating non-toxic liquid, and a sac attached to the counter casing acts as a balancing membrane, ensuring the pressure of the liquid in the counter equals that of the external water. The counter window is inside the meter body in the direction of flow for simplified reading. Tamper proof operation The V100 offers unrivaled resistance to illegal tampering: its unique conical body-half design eliminates the risk of dis assembly whilst in service and the mechanically driven cyclometer-type counter is resistant to magnetic interference. An optional return reverse flow restrictor provides further protection against outside interference, preventing the meter being operated in the reverse direction to reduce

Multi-jet meters and Single Jet Water meters
Multi-jet meters
are very accurate in small sizes and are commonly used in 5/8" to 2" sizes for residential and smaller commercial uses. Multi-jet meters use multiple ports surrounding an internal chamber, to create a jet of water against an impeller. The impeller rotation speed is in relation to the velocity of water flow. Multi-jets are very accurate at low flow rates, but are not used in larger sizes, since they don't have the straight-through flow path needed for the high flow rates used in large pipe diameters. Multi-jet meters generally have an internal strainer element that can protect the jet ports from getting clogged. Multi-jet meters normally have bronze alloy bodies or outer casings, with internal measuring parts made from modern thermoplastics and stainless steel.

Single-Jet Water Meter
Suitable water meter for domestic use
Volumetric Meter
Due to the volumetric rotary piston measurement principle. This meters can achieve the highest levels of reading accuracy even at the lowest flow rate.
also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the world and are used for almost all meter sizes up to and including 40 mm (1 1/2").
The piston meter operates on the principle of a piston rotating within a chamber of known volume. For each rotation, an amount of water passes through the piston chamber. Through a gear mechanism and, sometimes, a magnetic drive, a needle dial and odometer type display are advanced.

Type Of Water Meter
We can find two major methods of flow measurement in use, this types are
- Displacement
- Velocity
Displacement
This type of water meter is most often used in residential and small commercial applications. Displacement meters are commonly referred to as Positive Displacement, or "PD" meters. Two common methods of positive displacement measuring are Oscillating Piston meters and Nutating Disk meters. Either method relies on the water to physically displace the moving measuring element in direct relation to the amount of water that passes through the meter. The piston or disk moves a magnet that drives the register.
PD meters are generally very accurate at low to moderate flow rates typical of residential and small commercial users, and are common in sizes from 5/8" to 2". Because displacement meters rely on all water flowing through the meter to "push" the measuring element, they generally are not practical in large commercial applications requiring high flow rates or low pressure loss. PD meters normally have a built-in strainer to protect the measuring element from rocks or other debris that could stop or break the measuring element. PD meters normally have bronze, brass or plastic bodies with internal measuring chambers made from molded plastics and stainless steel.
Main Type of Displacement Water meter.
Velocity
A velocity-type meter measures the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. There are several types of meters that measure water flow velocity to determine totalized usage. They include jet meters (single-jet and multi-jet), turbine meters, propeller meters, and mag meters. Most velocity-based meters have an adjustment vane for calibration of the meter to required accuracy standards.
