E + H mass flowmeter is basically a Coriolis mass flowmeter produced by E + H, which measures mass flow, density, temperature and viscosity at the same time.
Coriolis measurement principles are widely used in various industries, such as life science, chemical, petrochemical, oil and gas, food industry, and can also be used in measurement transfer applications. Coriolis mass flow meters can be used to measure almost any fluid: cleaning fluid, solvent, fuel, crude oil, vegetable oil, animal fat, rubber, silicone oil, alcohol, jelly, toothpaste, vinegar, ketchup, salad dressing, gas or liquefied gas.
Coriolis flow measurement principle
Each Coriolis mass flowmeter has one or more measuring tubes to form a vibration system, which generates vibration artificially. When the fluid flows in the measuring tube, the inertia of the fluid generates a force acting on the wall of the measuring tube. The two phase sensors detect changes in the vibration of the measuring tube in time and space, the "phase difference". The difference is used directly as a mass flow measurement.
in addition, the fluid density can also be determined on the basis of the oscillation frequency of the measuring tube. The temperature sensor outside the measuring tube wall can measure the temperature of the measuring tube for temperature compensation. The measured process temperature may be used as the output signal.
advantage
Universal measuring principle for liquids and gases
Multivariable measurement: simultaneous measurement of mass flow, density, temperature and viscosity
High measurement accuracy: typical value is ± 0.1% o.r.; optional: ± 0.05% o.r. (PremiumCal)
The measurement principle is completely independent of the physical properties of the fluid and the flow field
No length requirement for front/rear straight pipe section
