FR-500R Ultrasonic calorimeter

    The air conditioning unit
    - thermal heating
    The water treatment industry
    The ci
    The shell is made of high-grade aluminum, surface spray, corrosion resistance, anti-oxidation
    At the same time, metering flow rate, flow rate and heat (cold) quantity
    The accuracy of the time difference principle is 0.5%
    The core device MCU, amplifier, two or three pole tube are all imported products, high performance, more powerful
    The German brand standard platinum resistance, the temperature error of + 0.1
    You can select a variety of sensors, such as clip, insert, or tube
    The temperature of the high temperature sensor can reach to 160C

FR-500R fixed type ultrasonic heat meter is measured by water flow ultrasonic flow sensor and the temperature sensor, and the backwater temperature difference, and the release or absorption measurement and display system of heat flow through the heat exchange, can be displayed at the same time, the instantaneous flow velocity, flow / heat / heat accumulation, water supply and return temperature; using the most advanced digital signal analysis method, can measure the clean and most turbid liquid without drift measurement; almost all components are used in well-known international manufacturers, circuit board by the large-scale production line automatic welding, advanced production technology, strict quality management of the whole instrument defect rate to a minimum; selection of new aluminum casting shell, non renewable materials added, strong, lightweight characteristics; surface coating processing, high-grade appearance, after more than 500 hours, 1000 hours salt fog test, damp heat test, adapt to long-term outdoor use; provide professional fixture clamp on sensor, fast and reliable. Select insert type sensor can achieve the best accuracy, and can not cut off the water supply with pressure mounting, under the premise of correct installation, insert the sensor accuracy is better than 1%, it will not cause blockage, obstacle and pressure loss. Because there is no components would result in accumulation and pollution, it contains no moving parts to wear out, so the first time after successful installation of future need very little maintenance; platinum resistance temperature transducer used in Germany famous brand, error of + / - 0.1, so as to ensure accuracy of instrument; FR-500R ultrasonic heat meter is widely used in heating, air conditioning unit, ground source heat pumps, hot and cold exchange system occasion.
