Introduction: The PD-200L series ultrasonic flowmeter is used for long-term online measurement of various liquid flows. The protection level of the host reaches IP67, and the protection level of sensor reaches IP68. The host and sensor are installed separately. The host can be installed indoors, instrument cabinets, dashboards, and sensors. On the measurement pipeline, the host and the sensor are connected with an ultrasonic flowmeter special cable to achieve flow measurement, and the temperature sensor can be connected to achieve heat measurement. It is widely used in tap water, heating, water conservancy, metallurgy, chemical industry, machinery, energy and other industries. It can be used for production monitoring, level debugging, heating network balance debugging, and energy saving monitoring. It is an important flow measurement instrument in the production process. Features: 1. The measurement accuracy is up to 1% 2. The protection level of the host reaches IP67, and the protection level of the sensor reaches IP68. 3. The measurement range is large, which can realize the measurement of pipes with diameters of DN15-DN6000. 4. The host has multiple installation methods: wall-mounted installation, rail installation, and explosion-proof box installation. 5. Equipped with a temperature sensor to achieve heat measurement.
