Accuron 7700 - Eastech Flow Controls

ACCURON ® 7700PARTIALLY FILLED CLOSED PIPESInline Cartridge MetersThe Accuron 7700 is an Inline CartridgeMeter specifically designed for partiallyfilled closed pipe applications. A 304stainless steel spool-type Cartridge,incorporating a trapezoidal flume,ultrasonic level sensor, and a pair of transittimevelocity sensors is manufactured tomeet exact customer laying length and endconnection specifications. During periods of minimal flow (Zero to 1/3 pipe),measurements are achieved through a highly efficient combination ofa trapezoidal flume (traceable to Bureau of Reclamation WinFlumestandards) and an ultrasonic level sensor enclosed within an “above theflow” protective casing. During periods of maximum flow (1/3 to fullpipe), measurements are achieved through proven area-velocity methodsby combining a pair of chordal transit-time velocity sensors with the same“above the flow” ultrasonic level sensor.The bi-directional transit-time velocitysensors also allow for monitoring of reverse and stagnant flow conditions.Each Cartridge is provided with an inspection port located directly above thetrapezoidal flume for calibration verification. Should the need ever arise forcleaning or replacement of a sensor, level sensor access is provided througha flange located on top of the protective casing. Velocity sensors are simplyremoved and cleaned through the utilization of isolation ball valves integratedwithin each sensor housing.This highly efficient maintenance feature eliminatesthe requirement for Cartridge removal or dewatering of the system.LOW FLOW(0 to 1/3 Pipe)HIGH FLOW(1/3 to Full Pipe)Level SensorInspectionPortTrapezoidalFlumeVelocity Sensors304 StainlessCartridgeVelocity SensorsPVC/304 StainlessSensor CableTriax w/PVC CoatingCable LengthMax: 1000 feetOperating Temp. -40° F to 158° F (-40° C to 70° C)Ball Valve Bronze (2”)Level SensorPVCSensor Cable4 Cond. w/PVC CoatingCable LengthMax: 1000 feetOperating Temp. -40° F to 158° F (-40° C to 70° C)

METER SPECIFICATIONS (Bi-directional)FACTORYPROGRAMMEDFLOWMETERSPre-programmed at thefactory for specific customerapplications, the Accuron flowmeter is a highly advancedmicroprocessor-based ultrasonic flow transmitter forextremely precise measurement of flow in open channels.DATA LOGGINGThe Accuron has a built-in datalogger with eight distinct channels for loggingflow and totals.The storage capacity for a single channel at 5 minute intervalsis 113 days. Logger data may be visually accessed on the display of the meterin pre-programmed time intervals or retrieved through a laptop or optionalmodem installed within the enclosure of the meter.Daily Averages: Daily summary allows viewing of the previous eightdays. This includes times, dates, averages, minimums, maximums and totals.Logger Graph: In addition, a bar graph may be visually displayed on theAccuron. The graph will display the stored logger data in pre-programmedtime intervals.Data Retrieval: Logger data can be collected by using a laptopcomputer or an optional modem installed within the Accuron enclosure.ENCLOSUREStandardIP66 / Nema 4, 4X polycarbonate enclosureOptionalExplosionproof, Aluminum EnclosureClass I ,Grps.
