Comparison of domestic gas relay calibrator?
Flow rate test: Guoyi company is using ultrasonic flowmeter, the price is 5500 yuan, Super use of the flow gauge, the price is 300 yuan. Ultrasonic flowmeter is characterized by high prices, good repeatability, high precision can reach the decimal point after two. Flowmeter features are: installation complex, low precision (± 0.5), cheap. Volume test: Guoyi is a liquid level measurement device
From the test principle to analyze: the purpose of the test is the same 1. Flow rate tester 2. Volume test 3. Seal test. The test method is different
Gas relay calibrator currently has two domestic production. One is Wuhan Hengxin Instrument Technology Co., Ltd. (referred to as the instrument) automatic gas relay calibrator, and the other is Kunming Super Power Equipment Co., Ltd. production of portable gas relay calibrator, the two have occupied the domestic market 80% Of the share. Now compare the two calibrators.
