The constantly growing penetration of automation and computerized data processing into water usage, in agriculture, industry, urbanic water supply systems and any other field where more is required than just the traditional mechanical register of water meters, creates a high demand for measuring instruments which are able to provide electrical information about the flow.Arad Water Meters equipped with electrical output devices combine the high reliability of the hermetically sealed, magnetically driven register with a wide variety of electric output options.All existing Arad Water Meters with magnetic registers can be easily upgraded to include electrical output.
• Application Examples
1. Remote ReadingIn combination with a remote reading system, or computerized data acquisition system, it is possible to collect and process water usage data in multi-apartment houses, in places with no access, or wherever it is required to bring all data to one point.
2. Flowrate MeasuringWith the appropriate type of electrical output it is possible to obtain on-line information about the flowrate which can be displayed, stored or both.
3. Flowrate ControlWith the appropriate type of electrical output and additional electronic control device it is possible to perform various functions like the operation of valves, pumps or alarm signals according to various preset levels of flowrate.
4. Bi-directional Flow MeasurementWith the appropriate electrical output and an additional electronic module it is possible to distinguish between flow directions, to measure and record flow rates and volumes passed in each direction.
5. BatchingFeeding electrical output to a batching controller enables pre-setting and delivering of accurate volumes of water in irrigation systems, industrial process etc.

• Transducer Types - Description & Specifications1. Reed Switch (EV) Sensor
A magnet activates this sensor. It acts as a “Dry Contact” and does not consume electric power. This is the most suitable sensor for “VOLUME” related functions and in such applications its operating life is practically unlimited (ca. 108 cycles).
Electrical specifications:a. Max. contact current - 50 mAb. Max. contact voltage - 48 V
2. Photo-Diode (EF) SensorThis sensor combines an IR light source and a light sensitive diode in one package. Signals are created by letting the light pass through, or reflected from a rotating element in the register in an interrupted mode. It requires a constant supply of power.
Electrical specifications:a. Currentsupplies-20•30mAthrougharesistor(seefollowingtableforvalues). Lead color code - yellow.b. Output - open collector. Max. Load - 2 mA. Lead color code - transparent.c. Circuit diagram:

1. VOLUME OUTPUT- Reed Switch1.1 SINGLE VOLUME OUTPUT
A 3 pointer register with magnet installed on one of them.Output definition: “Volume output”. Output type: EV.The reed switch sensor is installed in sealed transparent plastic cover that can be mounted on the register in any one of 3 positions facing the pointer with the magnet.3 values of output are thus available in 1:10:100 ratios.
1.2 IP 68 SINGLE VOLUME OUTPUTA 3-pointer register with a magnet installed on one of them.Output definition: “Volume output”. Output type: EV.The IP68 configuration is a sealed structure that can be mounted on the register shroud in a WSTsb Bayonet configuration in any of 3 positions facing the pointer with the magnet. 3 values of output are thus available in 1:10:100 ratios. Once assembled the IP68 configuration is fixed and sealed on the needed output.IP68 standard means that the assembly is totally protected against dust and protected against long periods of immersion under pressure.

1.3 DOUBLE OUTPUTA 3 pointer register with magnet installed on one of them.Output definition: “volume output”. Output type: EV-D.The output device contains 2 reed switches. All the components are sealed within a plastic module.A unique feature of this unit is the immunity from conditions that might create false pulses due to back and forth fluctuations of standing water in pipe line containing air pockets, or where mechanical vibrations of the pipe exist.
2. VOLUME OUTPUT- Photo DiodeA 3 pointer register with a serrated wheel on the first pointer shaft for activating a photo-diode sensor.Output definition: “Volume output”. Output type: EF-P.The serrated wheel has 10 “teeth” creating 10 signals per revolution, each signal represents 1/10 the full-scale value at this position in the register.
3. VOLUME OUTPUT- Optical Encoder (OE)A 3-pointer register with a reflective half coated wheel on the first pointer shaft for activating a sensor.Output definition: “Volume output”. Output type: Open Drain.The reflective wheel has a golden coating on half of its area- creating one pulse per revolution output in a forward flow; there’s no output in a reverse flow.Each pulse presents one full-scale value at this position in the register.
4. FLOWRATE OUTPUT- Photo DiodeA 3 pointer register with a serrated wheel mounted on the central shaft of the register for activating a photo-diode sensor.Output definition: “Flowrate output”. Output type: EF.The sensor is installed and sealed within a transparent plastic cover. The high number of “teeth” and the relatively high speed of the central shaft create a rapid stream of signals in frequency proportional to the rate of flow. Fed into suitable electronic units these signals are translated into flowrate values that can be expressed in any desirable units.
5. DUAL PURPOSE ELECTRONIC- DPEElectronic register showing rate of flow and accumulated volume. The register has LCD with 6 digits. The register has interchangeable presentation (every 30 seconds) between the rate of flow and volume. Mounted inside stainless steel vacuumed encapsulated cup with glass lens, hermetically sealed IP 68. Can be installed on any Arad meter and hydrometer. Can be programmed for various units: Flow Rate: GPM, m3/h, liter/secVolume: Gallons, Cubic Feet, Acre Feet, m3
6. MULTI PURPOSE ELECTRONIC- MPEElectronic register showing three interchangeable displays (every 10 seconds) on LCD display (1 display of flow an 2 displays of accumulated volume), with high resolution and EV passive output.Mounted inside stainless steel vacuumed encapsulated cup with plastic lens, hermetically sealed IP67.Can be installed on any Arad meter and hydrometer.
