Ultrasonic flowmeter price, WL-1A1

Ultrasonic flowmeter WL-1A1 and weir tank is equipped with, mainly used to measure water flow channel having a free-flow conditions inside. Instrument work sensor is not in contact with the fluid to be measured, to avoid water contamination and corrosion in the channel, and higher reliability. WL-1A1 ultrasonic flowmeter features: ★ non-contact measurement: The sensor is not in contact with the fluid, not water corrosion and dirt. ABS sensor housing are sealed and resistant, alkali, corrosion resistance in wet environments long-term reliable operation. ★ direct measurement of the flow of water: the sensor directly measuring the flow of the water level, do not use the stilling well, you can prevent the use of static water wells, sewage suspended solids, such as silt clogging the communication pipe, resulting in quiet well and weir tank water level inconsistent, or because the winter ice to form a false level, resulting in the flow measurement error. WL-1A1 type flowmeter new features: ★ Serial output a variety of communication protocols: In addition to the existing RS-232, the new RS-485. After the adoption of the key set the baud rate, parity, coding agreement directly with the modem, GSM wireless communication module connected with the installation of the instrument as required in the GSM wireless communication module, can be an ordinary mobile phone, view the new Modbus meter data via SMS Protocol: ★ data storage record: can record two-year, month, day, hour history, plus a nine-hour-minute recording by pressing a button on the instrument panel, directly view the history, can also be equipped with a printer to print history by outside ★ Additional record: According to a recent environmental monitoring needs, the instrument provides four 4-20mA input. Other instruments may be 4-20m current signal access, such as COD, PH and so on. WL-1A. At the same time recording the history of other instruments. Data recorded by other instruments key to view, or remote communication. Flowmeter main technical indicators and parameters: 1, flow range: 10 liters / sec to 10 m / sec (equipped with the kind of weir tank, specifications decision); 2, total flow: 8 decimal, Man cleared automatically after tired; 3, flow accuracy: 5% (with the amount of water weir tank 1-3% of uncertainty, an additional 1 to 2% of instrument error); 4, the distance range: 0.4 to 2 meters (from within 0.4 meters from the bottom of the probe is blind); 5, distance error: ± 3mm; 6, water level resolution: 1 mm; 7, Working temperature: -20 to + 50 degrees; 8, instrument protection: Probe to be flooded formula ; equipment is dust-proof; 9, remote signal: 4 ~ 20mA, RS232 serial output for remote communication; 10, AC or DC power supply: AC: 220V 50HZ 4W; DC: 12V 60mA (AC, DC exist, Meter with AC, AC power failure, automatically switches DC) 11, relay control: cumulative set m3 closure every time, level alarm, level limit, level limit options; SPDT type (normally open , normally closed)
