Features of the eYc gas flow standard calibration device


YUDEN-TECH is a minority company that can design own gas flow calibration system equipment in Taiwan, and uses the Venturi nozzle as the working standard of the gas flow measurement equipment. This equipment can not only be used to calibrate gas flow products, and also be used for production testing of own brand (eYc) flow products in the future. 

Select the flow rate and what quantity, is according to, the specified flow verification point of ISO 9300"Critical Flow Venturi Nozzle Flow Measurement". 
The working standard is the sonic nozzle, accuracy is up to 0.2%, and the flowmeter for check accuracy is 0.5%; and according to IEC 61298 and ISO 17025 standard to measuring 3-cycle curve.  

Our gas system can effectively improve the accuracy of the overall system through temperature compensation, pressure compensation, and humidity correction. In order to ensure the cleanliness of the gas and the durability of the device, the main pipeline is made of 304 stainless steel. Verification caliber capacity: DN15… DN150. Flow capacity: 1… 1000 m3/h. Different nozzle combinations can be used to calibrate different flow values; other environmental conditions such as temperature, pressure, and humidity are collected by the computer. Through core calibration technology, calculated the standard flow value and obtain the verification result.

Or we can add an air heater to simulate the environmental conditions of the product in the chimney pipe, to ensure that the product can keep the best accuracy during calibration.
