High precision of CMF series of Coriolis force mass flowmeter is mainly used to measure the instantaneous mass flow rate and cumulative mass flow, instantaneous volume flow and cumulative volume flow, at the same time also can display the medium temperature, medium density or concentration. It is mainly suitable for the following industries:
(1) he Toil industry, such as diesel, gasoline, heavy oil fuel metering; Crude oil output measurement, moisture content, the single well production; Crude oil loading and unloading metering, etc.;
(2) The chemical industry, such as toluene, xylene, butanone, cyclohexanone, n-butyl alcohol, isobutyl alcohol, methylene chloride, chloroform, liquid sulfur, lactam etc;
(3) The power industry, such as heavy oil, diesel fuel oil metering, slurry density meter limestone-gypsum wet desulphurization;
(4) The food, pharmaceutical industries, such as chocolate syrup, milk, fruit juice, pharmaceuticals, BPC (bulk pharmaceutical chemicals) measurement (clamp type healthy connection type);
(5) The energy industry, such as liquefied petroleum gas, natural gas, high pressure gas metering;
(6) In other industries, such as mortar measurement of solar silicon wafer multi-line cutting machine, measurement of pulp papermaking industry, power plant desulfurization serous densimeter, fine chemical raw material proportioning, asphalt measurement, etc.
Density measuring: Mediums of different density flow through the sensor, the vibration frequency of the vibration pipe is different, so can calculate the medium density by the vibration frequency. Temperature measuring: Platinum resistance Installed on the sensor vibration pipe can indirectly measured the temperature of the medium.Coriolis mass flowmeter working principle: All in one type composite explosion-proof flow meter, the sensor (primary meter) is essential safety; the transmitter (secondary meter) is explosion isolated. The sensor and the transmitter may all operate under hazardous area. Split type mass flow meter=mass flow transmitter+mass flow sensor
The structure of Coriolis Mass Flow Meters was consisted of a pair of bended tubes. The principle is to detect Coriolis force forced a pair of tubes from inner mass flow by fluid.
the essential safety flow meter, the sensor (primary meter) can operate under hazardous area, the transmitter (secondary meter) must only operate under prescriptive safety area (see section 3.2), forbidden to operate under hazardous area.How to install the Mass flowmeter?
