Wholesale of Nine Wave Open Channel Flow Meter

The physical quantity directly measured by the ultrasonic open channel flowmeter is the liquid level. When used for measuring flow in open channels, a measuring weir groove is installed on the open channel. The measuring weir channel converts the flow rate in the open channel into the height of the liquid level open channel flowmeter. The open channel flowmeter measures the water level in the measuring weir groove, and then calculates the flow rate based on the corresponding water level flow relationship of the measuring weir groove Ultrasonic open channel meter, durable and long-lasting. Beijing Jiubo open channel flowmeter is well-known in China and can be considered as the * open channel flowmeter.

Instructions and Introduction for Ultrasonic Open Channel Flow Meter:

1. Flow range: 10 liters/second to 10 cubic meters/second (determined by the type and specifications of the measuring weir used)

2. Accumulated traffic: 8-bit decimal number, automatically returns to zero after accumulating 8 digits, recalculated

3. Flow accuracy: ± 5% (with an uncertainty of 1-3% for the water measuring weir, plus an additional 1-2% instrument measurement error)

4. Ranging range: 0.4-2 meters (within 0.4 meters from the bottom of the probe is a blind spot, and within 0.4-2 meters is the ranging range)

5. Distance measurement accuracy: ± 3mm (calibrated within a 1-meter range)

6. Liquid level resolution: 1mm

7. Working environment temperature: -20~55 ℃ (AC power supply, and additional self tracing in the instrument can be: -35~55 ℃, additional self tracing should be declared at the time of ordering)

8. Instrument protection level: Instrument display part: IP66 (the wire hole at the bottom of the instrument should be blocked); Probe part: IP68

9. Power supply:

AC power supply: 220V ± 10% 6W (26W when using instrument self tracing)

DC power supply: 12V ± 2V120mA (when powered by DC, the instrument does not have 4-20mA output and the relay is not activated)

When AC and DC power supply coexist, the instrument uses AC power supply; AC power failure automatically connects to DC.

10. Timing error of instrument calendar clock:<5 minutes/month

11. Instrument data storage capacity: Monthly, daily, hourly records: only records traffic>2 years, additional instruments 4 channels>4 months per minuteRecord: Only record flow>8 hours, add other instruments 4 channels>4 hours

12. 4-20mA current connected to other instruments: internal sampling of the instrumentResistance: 200 Ω; The number of connections that can be made between the negative terminal and the instrument ground terminal: I1, I2, I3, I4, a total of 4 channels

13. Compatible printers: interface socket, DB25 socket set to "print records": EPSON compatible (recommended to use TP - μ p40T) settingFor "timed printing": only TP - μ p40T (requires the Chinese character library inside the printer).
