ELSTER KENT HELIX H4000 BULK WATER METER …

1 ELSTER kent HELIX H4000 bulk WATER METER RANGEA ccurate, Reliable and Robusthe ELSTER kent HELIX H4000 is a Woltmann-type METER designed for measuring bulk flows of cold potable WATER forrevenue billing in commercial or industrial applications anddistribution system powder coatedbody and surface rotor bearings -tungsten carbide and mass rotor withhydrodynamic thrust length flowstraightening vanesTMultiple pulsed output for increased management informationExtended low and high flow performanceWater temperature up to 50oCSuitable for forward and reverse flow meteringRobust shroud and copper can registerfor long life and clear readabilityLonger wear life for optimum accuracyExceeds

2 Class B specification in forward direction and for sizes up to 150mmin reverse directionInductive Pulse OutputsPressure TappingFeatures150mm200mm300mmAvailable in ten sizes for flow rates between m3/hand 2000 m3/h, the H4000 operates at temperatures upto 50oC and a maximum working pressure of 16 is maintained in both forward and reverse flow,and various register options are available to suit differentapplications. The METER complies with all relevantinternational quality standards, substantially exceedingISO4064 BS5728 Class B specifications for forward flowinstallations in horizontal, vertical and inclined flow meteringAvailable in sizes up to 150mm, reverse flow metering aidsnetwork management and ensures accuracy in revenuebilling constructionLike all ELSTER meters , the HELIX H4000 is manufactured fromthe highest quality materials for maximium resistance towear and corrosion.

3 METER body and cover are epoxy powdercoated for protection in all environments. Thrust pads andstub spindles are manufactured in tungsten carbide andjewelled rotor bearings are used for maximum wear life. Allwetted materials are UK WRc approved against health strainerThe use of an ELSTER in-line strainer isrecommended to protectthe rotor and help reducethe effect of inductive pulse outputs 40mm - 100mmPrimary 1 pulseper litreSecondary 1 pulseper 10 litresBi-directional inductive pulse outputs 150mm - 300mmPrimary 1 pulseper 10 litreSecondary 1 pulseper 100 litres250mmHighly robust ELSTER PR7 solid state pulsers form the bases of an ultra reliableAuomatic METER reading (AMR) system.

4 Combining the inductive technologyof the PR7 with ELSTER 's Emeris system generates one of the industry's mostadvanced and reliable AMR installations.

5 1 Understanding theoutputsPR7 pulsers have outputs designed for every need. Each pulser has both primary and secondaryoutputs. The use of each output is highlighted below, together with diagrams showing examplesof the pulse outputThe primary output has two wires: one carries pulses when the METER is operating in both forwardand reverse directions; the other is a direction flag. This is suitable for use with bi-directionalcounters, Emeris AMR systems and with data loggers. Use it with ELSTER 's ScanCounter (in bi-directional mode) in a fully bi-directional remote display and touch read outputThe secondary output also has two wires: one carries a pulse stream that compensates for anyreverse flow; the other indicates compensation is in process.

It should only be used withdata loggers which are capable of registering 5ms pulses.
