Online open channel flowmeter * Jiubo brand open channel flowmeter, wholesale agent of Jiubo open channel flowmeter, professional production agent of ultrasonic open channel flowmeter series products, high measurement accuracy, good reliability performance, strong stability, *. Beijing Jiubo WL-1A1 ultrasonic flowmeter, a registered ultrasonic open channel flowmeter by the environmental protection department, can be equipped with a Bacher groove.
WL-1A1 online ultrasonic open channel flowmeter simple operation instructions introduction:
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 ± 2V 120mA (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 minute Record: Only record flow>8 hours, add other instruments 4 channels>4 hours 12. 4-20mA current connected to other instruments: internal sampling of the instrument Resistance: 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) setting For "timed printing": only TP - μ p40T (requires the Chinese character library inside the printer).
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 online ultrasonic 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
