Product Description:

The AF300 series intelligent spiral vortex flowmeter is an improved product launched by our company. It can automatically and accurately detect the temperature, pressure, and flow values of the measured medium, and can automatically compensate for temperature, pressure, and compression factor. And it directly displays the volumetric flow rate of the medium under standard conditions (Pb=101.325kPa, Tb=293.15K). It is an ideal instrument that can display various parameters on-site and has multiple signal remote outputs. It can be widely used in various gas metering and flow control applications in petroleum, chemical, metallurgical, pharmaceutical, and urban gas transmission and distribution networks. Typical applications: High flow rate gases such as natural gas, coal to gas, compressed air, etc.

Technical parameters:

◆ No mechanical rotating parts, not easily corroded, high reliability, no maintenance required for long-term operation.
Built in pressure, temperature, and flow sensors with high safety performance, compact structure, and beautiful appearance.
Adopting a new type of signal processing amplifier and unique filtering technology, the interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference ability of the flowmeter, making the instrument integration and reliability higher, and the operation more accurate.
◆ Unique pressure and temperature sensor fault self diagnosis function, and can be displayed clearly and concisely on the LCD screen through settings.
According to the flow signal, the instrument coefficient can be automatically corrected in eight sections.
Low installation requirements for the front and rear straight pipe sections of the flowmeter (≥ 3DN for the front and ≥ 1DN for the rear);
◆ Ultra low power consumption, one 3.6V lithium battery can be used continuously for more than 3 years, and has a battery undervoltage alarm output function, which is more suitable for use with IC card management systems;
The unique function of time display and real-time data storage ensures that internal parameters are not lost in the event of power failure and can be permanently saved.
The instrument has explosion-proof and protective functions.
◆ -35~+80 ℃ full view large LCD display, the meter head (square) can rotate freely from 0 ℃ to 300 ℃, making installation and use simple and convenient. And it has password protection function to prevent parameter modification.
The signal output can be a three wire pulse signal, a two-wire or three wire 4-20mA current signal, and RS485 communication output. This series of products is subject to the national implementation of JJG198-1994 "Verification Regulations for Velocity Flowmeters".

Application scope:

Petroleum, chemical, textile, metallurgy, mining, light industry, medicine, electricity, environmental protection, municipal, food and scientific research fields, etc
