Introduction: Ultrasonic flow meter is a meter that measures the flow of liquid in a round pipe based on the principle of time difference method. It adopts advanced signal simulation processing technology and error correction technology to make the flow meter more adaptable to the environment of the industrial site, and the measurement is more convenient, economical and accurate. Ultrasonic flowmeter is a non-contact instrument, which can measure the flow of medium with large pipe diameter as well as the medium that is not easy to contact and observe. Its measurement accuracy is very high, and it is almost free from the interference of various parameters of the measured medium. It can especially solve the flow measurement problems of strong corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot. Used in petroleum, chemical industry, metallurgy, electric power, water supply and drainage and other fields. Be applicable: Municipal water supply Water treatment industry Heating and heating pipe network Calorie metering Features: 1. The installation form is flexible, and it can be installed by inserting, external clamp or pipe-segment sensor 2. Using time difference principle, high accuracy, up to 1.0% 3. The core components of MCU, operational amplifiers, diodes, etc. are selected from high-quality global suppliers, with high performance and more powerful functions 4. The host is fixed and wall-mounted, with an optional engineering plastic shell, which has strong moisture resistance and corrosion resistance 5. Fault self-diagnosis function, settings and data will not be lost after power off technical parameter: Principle: Ultrasonic time difference principle, 4-byte IEEE754 floating point arithmetic Accuracy: better than ±1% Display: 2×10 backlit Chinese characters or 2×20 character LCD can be connected, supporting Chinese, English and Italian languages Signal output: 4～20mA current output, impedance 0～1K, accuracy 0.1% OCT pulse output (pulse width 6～1000ms, default 200ms) Relay output Signal input: Three-wire PT100 platinum resistance can be connected to realize heat measurement Communication interface: RS485 communication, support MODBUS and other protocols Pipe material: steel, stainless steel, cast iron, cement pipe, copper, PVC, aluminum, glass fiber reinforced plastic and other dense pipes, lining allowed Caliber range: DN15～DN6000 Straight pipe section: The sensor installation point is best to meet: upstream 10D, downstream 5D, 30D away from the pump outlet (D is the pipe diameter) Types: water, sea water, industrial sewage, acid and alkali, alcohol, beer, various oils, etc., a single uniform liquid that can conduct ultrasonic waves Temperature: Temperature: -30～160℃ Turbidity: 10000ppm and the bubble content is small Flow speed: 0～±10m/s Temperature: Host: -20～60℃; Flow sensor: -30～160℃ Humidity: host: 85% RH; flow sensor: can be immersed in water, water depth ≤ 2m (Note: after the sensor is filled with glue)
