Since “Electronic Digital Blending System” was developed, the control accuracy of “In Line Pipe Blending System” has been remarkably improved, and this fact has required the improvement of flow measurement and development of temperature compensator for volumetric flow meter.
As the temperature compensator, the electronic device is most desirable by virtue of its high stability and solid state construction, especially.
The temperature compenstor for volumetric flow meter in this report is an electronic device which is constructed by comparatively simple elements and operates independently on flow rate.
This device consists of digital acaler, electronic counter, voltage to frequency converter and pulse subtractor.
This device has 0.1% accuracy, less than 10 rangeability and operates at less than 5, 000c/s input pulse frequency.
