Product advantages:
Adopting imported precision bearings specifically designed for instruments, with good wear resistance and high stability.
Reliable electromagnetic compatibility design, good anti-interference performance, and high reliability.
The body adopts stainless steel precision casting process, with high strength and good corrosion resistance.
Adopting a low-power design, it can be powered by lithium batteries and can also be connected to an external power source.
Product Features:
The body adopts stainless steel precision casting technology, with high strength and good corrosion resistance.
Integrated with a microprocessor, temperature sensor, and pressure sensor, it directly measures the flow rate, temperature, and pressure of the measured medium, and automatically performs temperature and pressure compensation and compression factor correction calculations for the flow rate.
The use of the new fourth generation tunnel magnetoresistance technology signal sensor (TMR) greatly enhances the instrument's ability to resist electromagnetic interference.
Adopting a low-power design, it can be powered by lithium batteries, which can be used continuously for more than 5 years; It can also be connected to an external power source.
The instrument has pulse signal output, 4-20mA analog signal output, and RS485 (MODBUS-RTU protocol) communication output; At the same time, there is also IC card signal output, which can be used in conjunction with IC card prepaid systems for easy trade settlement.
■ Dedicated LCD display screen (with backlight), intuitive and convenient reading, can simultaneously display instantaneous flow rate under standard conditions, instantaneous flow rate under working conditions, cumulative flow rate under standard conditions, as well as temperature, pressure and other parameters of the measuring medium.
■ It has real-time data storage function, which can prevent data loss when the instrument suddenly loses power. In the event of a power outage, internal data can be saved for a long time.
Reliable electromagnetic compatibility design, good anti-interference performance, high reliability, meeting the electromagnetic compatibility experimental requirements of JJG1037-2008 standard.
■ Detachable fully enclosed movement (Zhuanli number: ZL201420591807.2) structure, strong anti impurity ability, high precision, and low pressure loss; Good interchangeability.
Adopting imported precision bearings specifically designed for instruments, with good wear resistance and high stability; At the same time, it increased the lower sensitivity of the instrument and reduced the starting flow rate.
