The cooling is a key factor to raise the efficiency of automobile engine.
The radiator is cooled by air from radiator grille.
The thermal type flowmeters have been used for this service. One disadvantage of thermal type is to measure flow components from all directions.

The ultra- light and small vane wheel sensor solved this task by measuring only flow portion perpendicular to the radiator. The rotation frequency of vane wheel (RS-1000) is detected by an optical sensing system (RS-2000/3000), and is converted into wind velocity with the converter for radiator anemometer.
The converter for radiator anemometers has been provided in two types: a standard functional type(RR-5000) and a high setting functional one (RR-5000B). The converter has the functions of flow rate/ frequency indication, analogue voltage output and communication.
The air flow data of a maximum of 64 channels are collected with PC data gathering system (RW-1000) by connecting air flow converters to a RS232 converter (RU-1000).
Actual driving test can be conducted if a whole system is loaded in the vehicle.
This system has been appreciated by many customers as the development support system of automobile radiator, radiator grille and heat influence test of engine room.

Features

  • · Measuring Mass Flow

    Models TH-1700/1800 flowmeter measurement (shown in standard conditions) is not affected by any change of the pressure of the gas based on its measuring principle. large gas temperature fluctuation may only affect negligibly small deviation of its output that can be compensated by adding temperature measuring sensor.

  • · High Accuracy

    Model TH-1700 and 1800 flow meters provide accuracy of ± 1% of reading value for flow range from 5% through 100% F.S.

  • · Minute Flow Measurement

    Accuracy of ± 1% of reading value is achievable for minute flow, minimal flow to 0.2Nl/min.

  • · Wide Rangeability

    Line-up of meters of five (5) nominal sizes, 15mm, 20mm, 25mm, 40mm and 50mm, cover flow ranges from 0.2 Nl/min. through 4050 Nl/min.

  • · Low Pressure Drop

    Pressure drop generated by model TH-1700-CNG is equivalent to that of straight pipe. For model TH-1800-CNG that is provided with integrated flow straightener, pressure drop may reach 850mmH2O at maximum.

  • · Easy to Follow Variety of CNG Composition

    CNG composition change can easily be programmed into the convertor for five (5) components, each with 1Vol.% division.

  • · Availability of Measurement of Low Pressure Gas

    Measurement is available for gas pressure from 0 to 10 kgf/cm²G

  • · Durable Construction

    Meters are not subjected to deterioration due to wearing, etc., since there is no moving part inside of the meters. No periodical maintenance nor calibration may be required for its simple mechanical construction.

  • · Multi-functional Convertor

    The convertor is available to output and indicate Flow Rate, Integrated Flow, Integrated Flow for a gated time duration, time duration for a gated flow rate and Alarms, etc. A variety of output signals provides easy data communication to management com puters. A variety of setting capability provides measurements to satisfy the test requirements.
