detailed introduction of ultrasonic flowmeter
external clamp type or pipe section type digital display regulator manufacturer ultrasonic meter instrument should take "rate difference method" as its basic principle, instrument panel for accurate measurement of total liquid flow in round steel pipe. It selects digital display regulator wholesale multi-single pulse technology, data signal intelligent solution technology and error correction technology, so that instruments can be more integrated into the natural environment on the spot of industrial production, 
economic development and precision. Commodities to achieve standards, can be used in the market of crude oil, chemical plants, metallurgical industry, power engineering, water supply and drainage and other industries.
detailed introduction of electromagnetic flowmeter
electromagnetic flowmeter (Electromagnetic Flowmeters, known as EMF) is a new type of total flow detection instrument with the rapid development trend of electronic information technology in the 50~60 era of the 20 new century. Electromagnetic flowmeter is an instrument and equipment that uses the magnetic effect of current to accurately measure the total flow of conductive fluid mechanics according to the electromotive force induced by conductive fluid mechanics and electromagnetic field.
Ultrasonic flowmeter and inductive steam flowmeter are all universal high-precision metrological verification instrument panels, which have been recognized by China's General Administration of Quality Supervision and Quality Supervision and other international relative testing centers. So what are their characteristics and advantages and disadvantages?
characteristics of electromagnetic flowmeter:
1) the controller structure of electromagnetic flowmeter is simple and clear, accurate digital display regulator supply there is no fitness moving component outside the measuring tube, there is also no throttle valve member to block hydrodynamic flow.
2) It can accurately measure the total flow rate of stain substances, corrosive substances and suspended liquid-solid two-phase flow, and cannot accurately measure non-conductive fluid mechanics. 3) The output of the electromagnetic flowmeter is proportional only to the average water flow rate of the measured fluid.
4) The electromagnetic flowmeter has no inertial force of mechanical equipment, and can accurately measure the total flow of instantaneous pulsation, and can also accurately measure the total flow in two directions of the front and back. 5) The accuracy class is 0.5; after laboratory calibration, it reaches 0.25.
6) Electromagnetic flowmeters are very susceptible to interference signals and have zero drift. They must be calibrated every 2 years. 7) Electromagnetic flowmeters are complex to install, and the associated equipment requires expansion joints and control valves.
