Working principle
A gas rotary rotary flow meter works by introducing gas into the inlet, which drives the rotor to rotate. Each rotation produces a fixed volumetric flow rate that is discharged from the outlet – this is the working principle of constant displacement rotation. The rotor’s rotation frequency is transmitted via a magnetic coupler, thus achieving flow detection or measurement. Furthermore, various structural forms are available to meet different user requirements.
Dual display type: It is equipped with both a mechanical counter and a flow compensator. The mechanical counter directly displays the cumulative amount under operating conditions, while the flow compensator realizes temperature and pressure correction. It directly detects and displays the temperature, pressure, operating volumetric flow rate and total volume, and standard volumetric flow rate and total volume of the medium.
Main features
-
Long service life
With a normal operating life of up to 15 years, the flow meter’s sophisticated design and craftsmanship, including precision machining and balancing of the rotor, high-strength surface treatment, wear-free rotation, contactless sealing, self-cleaning function, and excellent bearing lubrication, ensure long-term normal operation.
-
Wide range
The rangeability of flow meters of different specifications is 50:1 to 243:1.
-
High precision, high reliability
Permanent, high precision that requires no adjustment and is unaffected by changes in media conditions.
-
Extremely low initial traffic
The starting flow rate for different specifications of flow meters ranges from 0.06 (m³) /h to (1.20 m³) /h.
-
Small pressure loss
The pressure loss of flow meters of different specifications ranges from 0.07 kPa to 0.55 kPa.
-
Good versatility
All flow meter body components can use common accessories.
-
Good interchangeability
The accessories are interchangeable with the watch body components of the same specifications.
-
A new rotary detection technology is used to detect the rotational speed of the flow meter wheel.
It can completely solve the problems of mismeasurement and pulse signal loss caused by pulsating flow, and ensure the numerical synchronization between the compensator and the mechanical counter.
Scope of application
It is widely used for flow measurement of gases such as natural gas, coal gas, inert gas, and air, and is an ideal flow measurement device for urban gas, oilfield chemical, and scientific research departments at home and abroad.
It is widely used in the trade metering of urban gas, and is especially suitable for trade metering of large gas users such as government agencies, schools, enterprises, hotels, and restaurants. It can also be used in main metering, gas distribution stations, and main gas supply stations for various industrial raw materials.
