Velocity area method ultrasonic flowmeter AVFM6.1

Typical applications:

waste water

rain

sewer

irrigation water

overview:

1. The flowmeter consists of an immersion ultrasonic sensor, a connecting cable, and a controller with display, transmission, accumulation, and recording functions. The system has no movable parts.

2. The liquid level measurement accuracy is reading0.25% or 2mm, take the larger value. Repeatability is 0.1%, flow rate measurement accuracy is ± 2% or ± 1.2cm/s of reading, taking a larger value. The minimum size and diameter of solid particles in the fluid are required to be 100 microns and the minimum concentration is 75ppm.

3. Applicable to non-full, arbitrary rules or non-rule channels

sensors:

1. Maximum permanent immersion depth:4.57m

2. Doppler velocimetry principle, flow velocity range:0.03-6.2 m/S, the reverse maximum measurable flow rate is-1.5 m/s

3. Using the ultrasonic echo ranging method, the fluid level range of the immersion sensor can be measured as follows25.4mm to4.57m

4. The liquid level measurement circuit system is integrated with a temperature sensor to automatically compensate for the temperature.

5. The sensor is composed316 stainless steel and epoxy resin composition

6. The sensor operating temperature is:-15℃-80℃

sensor connection cable

multi-core shielded waterproof cable, standard length is7.6m, can be extended152 rice

controller

1. The controller can provide calibration on site for circular pipes and open channels of any shape.

2. Through its own5 the system is configured by keys and parameter selection menu, and the system is calibrated by parameter codes.

3. Configuration data is password protected and stored permanently in power failure12 within months

4. The field configuration can select or automatically convert the measuring unit, measuring range, high/ low flow alarm relay, flow proportional relay pulse rate

5. In the case of large flow fluctuations, the transmitter can independently stabilize the liquid level and flow rate to output a more stable flow value

6. Transmitter operating temperature-20℃-60℃, the internal comes with a thermostatic control heater to protect condensation at a temperature of -1 ℃

7. Transmitter owns3 road independent4-20mA output, maximum load1000 ohm, can also be selected0-5VDC output mode. The output can be configured as liquid level, flow rate and flow rate.

8. Two programmable5 ampere solid state relay, can be used* * * * * * * accumulator, high and low flow alarm, flow rate or liquid level alarm, and echo loss alarm.

9. With backlight LCD it can display the flow rate, liquid level, flow rate and relay status of the unit selected by the user,14 bit-digit cumulative flow, recorder status, sensor status.

10. Flow, calibration unit, cumulative flow, relay status, recorder status, sensor status can be observed without opening the transmitter housing.

11. Built-in recorder can record2600 ten thousand sets of data, through USB the interface can be transferred to an external storage device. The data logger supports records with time and date, and outputs formatted traffic reports, including total traffic, average traffic, minimum traffic, maximum traffic, and number of unexpected events. And data curve reports.

12. The device can store the past365 the minimum flow rate, the maximum flow rate, and the total flow rate per day. Data can be obtained through USB download directly to an external storage device and generate a report.

13. Device configuration parameters can be downloaded directly to external storage devices through the call menu.

14. Liquid level, Doppler signal strength can be downloaded to external storage devices through the call menu for diagnostic purposes.

15. The installation method of the wall surface of the transmitter is as follows IP66

17. Transmitter circuit to AC input, sensor,4-20mA there is surge protection.

18. The transmitter allows outdoor installation and can automatically detect optional accessories, including replaceable sensor configuration, serial communication, and additional control relays.

  Optional features:

1. independent submerged Doppler flow sensor and non-contact ultrasonic level sensor are installed above the fluid. The Doppler sensor can be designed for permanent immersion measurement, and the flow rate is0.03 m/s-6.2 m/s, reverse maximum measured flow rate-1.5 m/s. The measuring range of the non-contact level gauge is200mm-4.57m, built-in temperature compensation.
2. Optional Cable Length for Sensor15m
3. sensor optional30 meter cable length

transmitter optional9-32VDC DC power supply, low power consumption type. Maximum power consumption,10 watt.

Optional portable device
