Product Overview
ZYL flow metes are designed for metering non-corrosive gases (natural gas, air) in petrochemical, industrial, commercial, and research settings.The meters are compliant with EN12480 and OIML R137. The flow meter Operates on a fixed-displacement rotary principle to measure pipeline gas precisely, with a mechanical counter displaying volumetric flow.
Usage Conditions
Environmental conditions
Ambient temperature：-25℃~+55ºC
Relative humidity：5%~95%
Atmospheric pressure：70 kPa~106 kPa
Medium conditions
Medium temperature：-25℃~55ºC
Measuring media: various gases such as
natural gas and coal gas, as well as air, alkanes, and industrial inert gases.
Features
High Strength
Robust aluminum alloy housing with thickened walls ensures stress-resistant installation and long-term stability.
Optimized Rotor
Fully meshing arc-envelope rotor design delivers precise sealing and wide measurement range.
Extended Lifespan
Anodized key components resist wear/corrosion.
Non-contact sealing between rotor and housing guarantees durability.
Precision & Reliability
Imported bearings maintain permanent accuracy unaffected by media, ensuring consistent performance.
Wider Range
The range of different specifications can reach 250:1, even up to 260:1
Smaller Starting Flow
The starting flow rate of flowmeters with various specifications ranges from 0.02 m³/h to 0.7 m³/h.
Small Pressure Loss
The pressure loss of flowmeters of diverse specifications varies from 0.05 kPa to 0.8 kPa.
Various Structural Types
A.Basic type: withmechanicalcounter, display of cumulative volume flow under working conditions, and with low-frequency pulse generator. B.Intelligent type: Equipped with volume corrector, with functions of temperature, pressure compensation, wireless remote transmission, IC card, etc.
