Ultrasonic flowmeter - fixed wall mounted for a variety of long-term online measurement of the liquid, the host and the sensor separately installed, the sensor installed in the need to measure the pipeline, the host and the sensor with ultrasonic flowmeter dedicated cable connection, is currently the most widely used ultrasonic Flowmeter.
Temperature sensor, achieving hot (cold) metering function, the amount of hot (cold) for real-time monitoring.
Features: 1.High reliability: the use of low-voltage multi-pulse balanced transmission circuit, measurement accuracy, service life and high reliability 2.Wide range of measurement: the use of different types of sensors, can achieve caliber DN15 ~ DN6000mm pipe flow measurement 3.Data interface: RS485 serial interface, through the PC computer to upgrade traffic, support MODBUS protocol 4.Anti-interference ability: the use of dual-balanced signal differential transmission, receiving circuit, effectively resist the inverter, TV tower, high voltage lines and other strong interference 5.Powerful memory function: automatic memory before 128 days, the first 10 years of accumulated calories and traffic, the cumulative date and so on can be read through the MODBUS protocol 6.Heat measurement: with the temperature sensor, can be achieved heat (cold) measurement
Ultrasonic time difference principle, 4 bytes IEEE754 floating point operation.
better than ± 1%.
Can be connected to 2 × 10 backlit characters or 2 × 20 character LCD display, support in the English, Italian three in that language.
1 channel 4 ~ 20mA current output, impedance 0 ~ 1K, accuracy 0.1%. 1 way OCT pulse output (pulse width 6 ~ 1000ms, default 200ms). 1 relay output.
3 channels 4-20mA current input, precision 0.1%, can collect temperature, pressure, level and other signals. Can be connected to three-wire PT100 platinum resistance, to achieve heat measurement.
Isolated RS485 serial interface, through the PC computer to upgrade the flow meter, support modbus and other protocols.
Steel, stainless steel, cast iron, cement pipes, copper, PVC, aluminum, glass and other all-dense pipe, allowing a lining
15 ~ 6000mm
Water, sea water, industrial sewage, acid and alkali, alcohol, beer, all kinds of oil can carry a single uniform ultrasonic liquid
(-30--180) ℃ ultra-high temperature to be customized
10000ppm and the bubble content is small
0 ~ ± 10m / s
Host: -20 ~ 60 ℃; Flow sensor: -30 ~ 180 ℃
Host: 85% RH; Flow sensor: can be flooded work, water depth ≤ 2m (Note: after the sensor filling)
Built-in capacity of 2000mA rechargeable Ni-MH battery, each time fully charged for more than 15 hours of continuous use, the use of power adapter, can achieve uninterrupted measurement.
Custom twisted pair, under normal circumstances limited to 50 meters; use RS485 communication, transmission distance of up to kilometers.
The standard sensor is L2 sensor.
Optional flow sensor:
Outer clip type sensor: The installation of the sensor will be directly tied to the outer wall of the pipe under test, without breaking, no need to stop production, with security Installed simple, no pressure loss and so on.
Plug-in sensor: The installation of the pipe in the test on the use of special hole tool hole, the sensor and the measured medium direct contact measurement, the solution because the outer clip sensor in the measurement of thicker pipe is difficult to receive the signal and long time measurement signal Attenuation of the problem, with non-stop installation, maintenance-free, has nothing to do with the diameter, no pressure loss.
Pipe section sensor: A flange is used to connect the pipe section sensor directly to the pipe under test. It has the characteristics of high precision, good stability and maintenance.
