UNIQUE FEATURES OF ANDISOON MASS FLOWMETER
Mass flow meters are known for their high accuracy, wide measuring range and reliable performance, and have been successfully used in various industries over the past many years.
Unlike other instruments that are limited to measuring liquids at normal pressure and temperature, ANDISOON excels in measuring under challenging conditions, including high pressure, high viscosity, and high and low temperatures. For example, when measuring CNG (compressed natural gas), the difficulty lies in the high pressure.
However, ANDISOON's sensors can withstand high pressures, allowing the necessary increase in flow tube thickness, allowing the transmitter to detect signals with greater sensitivity. Therefore, ANDISOON's mass flow meters specially designed for CNG gas dispensers have been widely used in the market.
In the field of cryogenics, Andisoon has developed a backflow meter and a liquid phase injection meter for LNG refueling stations, with a minimum temperature of -196°C.
In the field of process control, Andisoon has developed a micro-bend type mass flowmeter, with a maximum flow rate of up to 300t/h, widely used in petroleum, chemical and other industrial conditions.
A. ANDISOON mass flowmeter directly measures the mass flow rate, it is measured in terms of standard volume alone. Bits provide output without the need to compensate for variable pressure or temperature in the flow computer.
In addition, because ANDISOON flowmeters have no wearable moving parts and calibration will not change over time,
changes, so they require no routine maintenance.
C. Can measure high pressure gas
The application of domestic mass flow meters is mainly concentrated in the field of liquid measurement, and there is no mature application in the field of gas measurement. On the basis of mastering DSP processing technology, our company complies with the needs of the industry and designs a high-precision mass flow meter suitable for high-pressure gas measurement, which is more suitable for the needs of the high-pressure gas measurement industry and has better performance.
D. Industry-leading high-pressure aging process
The high-pressure aging platform built by our company conducts aging tests on each CNG flow meter, providing an effective solution to the problem of measurement performance degradation that may be caused by changes in sensor characteristics due to long-term high pressure during later use.
E. Good zero point stability
Our company has designed a set of high-precision processing technology for the manufacturing of sensors to ensure the quality of the sensor, and its zero-point stability is not inferior to imported products.
F. Multi-parameter measurement technology
Our company adopts digital signal processing (DSP) technology. Compared with analog technology, front-end digital processing equipment significantly reduces signal noise and responds faster. It adopts 485 communication. The host side of the metering system can obtain the required relevant parameters through 485 communication. , such as: mass flow, volume flow, temperature, density, status and other information. For liquid applications, mass flow meters using multi-parameter measurement technology can achieve an accuracy of 0.2. The actual accuracy can be higher and the performance can be even better.
G. Self-diagnosis technology
In the actual application process, when an abnormality occurs in the flow meter, the fault code can be read through debugging software or handheld debugging equipment, which facilitates flow meter users to solve the problem more comprehensively and eliminate faults.
H. Supports standard industrial control communication protocols ModbusRTU, etc., making it easy to configure and use.
I. Industry-leading cryogenic calibration platform
In the process of LNG development, the company has built an industry-leading cryogenic calibration platform, using liquid nitrogen (-196°C) with a lower temperature than LNG as the calibration medium, providing a cryogenic solution for the development of LNG Coriolis flowmeters. Application experience. This calibration platform has now been used as the calibration platform for all the company's LNG flow meters, enabling real cryogenic calibration of each LNG flow meter to ensure the measurement accuracy of cryogenic applications.
J. Good scalability
The company can design and manufacture mass flow meters with special specifications and models and special functions according to user needs, tailor-made for users.
