Coriolis mass flow meter measurement principle and product shape and installation dimensions
Developed independently by our company patent product coriolis mass flow meter is a kind of advanced high precision mass flow meter, due to its superior performance, make the high accuracy of measurement, the fluid state requirements, low pressure loss and a variety of specifications of the coriolis force (hereinafter referred to as the coriolis force) instrument can be directly obtained by measuring the quality of the liquid or slurry flow, volume flow, density, temperature, without artificial calculation or estimate, even in poor working environment can show excellent performance, its internal no moving parts, does not need complex installation, also does not have stringent requirements for working condition,Each sensor is made of stainless steel, the output of the transmitter can meet your various needs.
The product is suitable for measuring almost all fluids without solid particles, mainly used in petroleum, chemical, food, environmental protection and other industries.
The implementation standard is:
JJG 897-1995 Verification regulation of mass flowmeter
JJG 1038-2008 Verification regulation of mass flowmeter
Measuring principle
LK type mass flow meter with double "Π" type sounding pipe to realize the differential signal detection, based on digital signal processor (DSP) is equipped with electronic switching device, sensor of digital closed loop control, digital signal processing, calculation and diagnostic functions in one, can online real-time measurement of fluid mass flow rate, density and temperature, has advantages of high accuracy and good reliability.Through RS485 interface (or HART interface) and direct communication with the computer, DCS, etc., in the special software environment, the user can directly on line node configuration, fault diagnosis and data recording.
LK series mass flow meters can be divided into two types according to tube type and purpose:
LKC mass flow meter is a special mass flow sensor designed for the measurement of compressed natural gas (CNG). It can be used in any gas feeder, and can also be used as a special sensor for cars or light and heavy vehicles.
LKD type mass flow meter is suitable for measuring almost all liquids without solid particles, mainly used in food, petroleum, chemical industry and other industries.
