  GKM KSM Volumetriccold water meters Key features ã Volumetric rotary-piston principle of measurement ensures registration even at the very lowest rates of flow with maintained accuracy over the flow range ã Unique grooved piston design ã Can be installed in horizontal, vertical or inclined pipelines without affecting accuracy ã The co-polymer resin manufactured body allows its use with absolute confidence where waters with aggressive or dezincification  properties exist ã Requires no calibration throughout its lifespanã ‘O’ ring seal placed between the measuring chamber and meter body ensures that internal leaks which could by-pass the measuring chamber are eliminated ã Use of advanced engineered plastics for the measuring chamber minimises wear and maintains reliability under all operating conditionsã Large surface area fine filter prevents damage by gathering solid particles. Due to its design, a partially obstructe filter will not affect the meter’s accurate registrationThe register is fully-sealed, vacuum filled, with a simple straight-reading presenta- tion. The number rollers are totally immersed in a non-toxic liquid which acts as a lubricant. The sac attached to the register casing acts as a balancing mem - brane and ensures the pressure of the liquid in the register is the same as that of the water inside the meter. The register is placed in a window inside the meter body in the direction of flow for easy reading. Performance figures for the KSM range meet the requirements of the ã OIML R49 ã ISO 4064ã EEC Directive 75/33/EEC following: Tamperproof The KSM offers oustanding resistance to illegal tampering. Its unique conical body-half design means it cannot be disassembled while in service and the mechanically-driven register cannot be interfered with magnetically. An individual serial number engraved in each body. Compliance with standardsRegisterOptional features Internal disc-type reverse flow restrictor can be included as aan optional feature. This reduces the possibility of water being run back illegally. Remote-reading The KSM operates as a standard meter untill the needs arises, and then by simply removing a plastic plug and inserting a magnetically operated signal sensor, it can be converted on location whilst still in use without any disconnection, risk of component damage or need to re-calibrate. The pluse provided by the probe can be used to step a remote register or in the longer term, the output can also be interfaced with a module which could be interrogated by a computer or other device. The KSM model is particulary suitable for incorporation in energy management system.   025151 Technical Specification: 15G ¾” A3.1252.50.0250.0156229999.999990.5 Meter size (mm) Meter thread sizeOverload flow ratePermanent flow rateTransitional flow rateMinimum flow rateStarting flow (approximate)Maximum registrationOutput pulseAll modelsQ 4 ±2%Q 3 ±2%Q 2 ±2%Q 1 ±5%m³/hm³/hm³/hm³/hl/hm³l/pulseTypical Pressure Loss CurveTypical Accuracy Curve    M  e  a  s  u  r  e  m  e  n   t   E  r  r  o  r   /   % Flow Rate / l/hFlow Rate / l/h    P  r  e  s  s  u  r  e   L  o  s  s   /   b  a  r  s Head loss at Q 3  less than 0.63 bar.Maximum water temperature 50°C.

George Kent(Malaysia) Berhad reserved the right to modify the specifications without prior notice. Care sholud be taken during installation to ensure that the meter and its connectors are not subjected to elongation, compression or bending forces.Allowance should be made for expected expansion and contraction of adjacent pipework.High installation stresses may eventually give rise to joint leakage or even permanent damage to the meter or its connections.
