Introduction: This product has the advantages of high measurement accuracy, strong anti-interference ability, stable and reliable operation, and abundant interfaces. Every part of the flowmeter is designed in accordance with the IP68 protection class standard, which can be used in harsh working environments. Features: 1. High-precision measurement The measurement accuracy is better than ±1%; 2. The measurement range is large and different types of sensors are used, which can realize the measurement of pipeline flow with a diameter of DN15~DN6000mm; 3. Easy to operate, you can use the magnetic bar to operate the menu on the host, and also support opening the cover to operate the menu through the four-button keyboard; 4. The powerful memory function automatically remembers the accumulated flow in the first 512 days, the first 128 months, and the first 10 years, and automatically remembers the time and flow of the first 64 calls and power failures; 5. The transmission distance is long and the networking is fast. RS485 bus communication can be used with ordinary cables, and the networking is very convenient and fast; 6. Heat measurement is matched with a temperature sensor, which can realize heat measurement. Technical parameter: Principle: Ultrasonic time difference principle. 4 bytes IEEE754 floating point operation Accuracy: flow rate; better than ±1%, repeatability better than ±0.5% Display: It can be connected to 2×10 backlit Chinese characters or 2×20 character-loaded liquid crystal display, and supports three languages: Chinese, English and Italian. The instantaneous flow and cumulative flow, instantaneous heat and cumulative heat, flow rate, time and other data can be displayed on the same screen. Signal output: 1 channel 4~20mA current output, impedance 0~1K. Accuracy 0.1% 1 channel OCT pulse output (pulse width 6~1000ms, default 200ms) 1 channel relay output Signal input: 3 channels of 4~20mA current input, accuracy 0.1%, can collect temperature, pressure, liquid level and other signals Can be connected to three-wire PT100 platinum resistance to realize heat measurement Data interface: isolated RS485 serial interface, the flowmeter can be upgraded through a PC computer, and supports MODBUS and other protocols Special cable: Customized twisted pair, generally limited to 50 meters Pipe material: steel, stainless steel, cast iron, cement pipe, copper, PVC, aluminum, glass fiber reinforced plastic and other dense pipes, lining is allowed Tube inner diameter: 15~6000mm Straight pipe section: The sensor installation point is best satisfied; 10D upstream, 5D downstream, 30D away from the pump outlet (D is the pipe diameter) Type of measuring medium: water, seawater, industrial sewage, acid and alkali, alcohol, beer, various oils and other single uniform liquids that can conduct ultrasonic waves Medium temperature: Temperature: -40~160℃ Medium turbidity: better than 10000ppm Medium velocity: 0~±12m/s Temperature: Host: -20~60℃: Flow sensor: -40-160℃ Humidity: host: 85%RH; flow sensor: can be immersed in water, water depth <2m (note: after the sensor is filled with glue) Power supply: DC8-36V or AC85-264V
