ULTRASonic energy meter 0.6 – 2.5 m3/hUltrasonic compact heat meter SHARKYModel 773DAtasheet ultrasonic compact energy metermodel 773GENERAL❑ Static compact energy meter with fully electronic measurementbased on the ultrasonic principle❑ Storage of volume and energy dataCOMPONENTS❑ Ultrasonic volume measuring component❑ Integrator with integral hardware and software for measuringflow rate, temperature and energy consumption❑ Temperature sensorsINTEGRATORThe integrator contains all the necessary circuits forrecording the flow rate and temperature and for calculating,logging and displaying the data. The integrator housing canbe mounted directly on the volume measuring componentor on the wall. The meter can be conveniently read from asingle-line 7-digit display with units and symbols. A pushbuttonprovides user-friendly control of the various displayloops. All failures and faults are recorded automatically andshown on the LC display. To protect the reading data, all therelevant data are saved in a non-volatile memory (EEPROM).This memory saves the measured values, device parametersand types of error at regular intervals.ULTRASONIC VOLUME MEASURING COMPONENTThe ultrasonic technology of the volume measuring componentpermits very high measuring accuracy and can be usedin the forward or return line. The volume measuring componentmeets the requirements of EN 1434 / class 2 and 3.The standard cable length between the calculator and thevolume measuring component is 1.5 m (5m optional).Supply voltage:❑ Lithium battery 3.0 V DC (12-year life)❑ Lithium battery 3.6 V DC (16-year life) optional❑ Mains unit 230 V AC or 24 V ACTEMPERATURE SENSORSPairs of Pt 100 or Pt 500 temperature sensors (Ø 5.2 mm)with 2-wire leads are used as a standard.INTERFACESSHARKY is equipped as standard with a ZVEI optical interfacewith the M-Bus protocol as per EN 1434. This interface isused, for example, for communication with the HYDRO-SETparameterization software. The meter features 2 slots forthe modules. One slot for the function modules, and one forthe communication modules.The following communication modules are available asoptions:❑ Real Data Radio Module❑ M-Bus module to EN 1434❑ RS 232 moduleThe RS 232 module is a serial interface and permits dataexchange with the heat meter. For this purpose a specialdata cable is necessary (please find order references).The Radio module communicates a list of predefined datarecords. This can be edited by HYDRO-SET.PULSE inPUTTwo additional pulse inputs are available. The pulse valueand the unit is configurable for energy, water, gas or electricalmeter by HYDRO-SET. Also two accounting day´s areavailable for both inputs.PULSE OUTPUTThe meter provides levels for two optional external pulseoutputs, which can be freely programmed using theHYDRO-SET software.Possible pulse output values❑ Energy (standard setting)❑ Volume (standard setting)❑ Tariff energy 1❑ Tariff energy 2❑ Tariff condition 1, limit switch❑ Tariff condition 2, limit switch❑ Energy error❑ Volume errormodule combinationsThe following module combinations for data transmissionare available ex works or for retrofitting in the field.Function modules:❑ Pulse input module❑ Pulse output moduleCommunication modules:❑ M-Bus or❑ RS 232 or❑ Real Data Radio
