Installation

Key install requirements. Full datasheet on request.

  • Run pipe full at the meter; pressurised dispenser feed only
  • Install upstream strainer; slow-fill at first commissioning
  • Maintain ≥ 10 D upstream and ≥ 5 D downstream straight pipe
  • Class IB service requires Ex d cable glands and flameproof junction box
  • Inspect impeller every 6 months; check K-factor against calibration certificate

Frequently asked questions

What is a gasoline turbine flow meter and how does it work?+
A gasoline turbine flow meter measures volumetric fuel flow through a free-spinning rotor. The LWGY covers Line sizes 1/2″ to 4″ (DN15 to DN100) for gasoline, jet fuel A-1, JP-5, JP-8, and light naphtha. Gasoline at 0.5 cSt sits well inside the LWGY range. Each meter ships with a factory K-factor calibration certificate for retail fuel-sales traceability.
When does turbine beat Coriolis or PD meter for gasoline?+
Turbine is the cost-effective pick for retail fuel skid, fleet refueling, and terminal loading where +/- 0.5% of rate meets the application and pulse output integrates with dispenser controllers and card readers. Choose Coriolis for custody-transfer accuracy above 50 m³/h where +/- 0.1% and density-corrected mass flow are mandated. Choose PD for very low-flow truck-loading-rack arms with start-stop transient cycles.
Can the meter handle aviation jet fuel A-1?+
Yes; Jet A-1 sits at 1.0 to 1.5 cSt at 40 °C, well within the LWGY range. The 316L body and 2Cr13 impeller handle Jet A-1, JP-5, and JP-8 chemistry without corrosion concern. Aviation refueling skids commonly run pulse output to fuel-card systems for automated invoice billing. Ex d ships standard with the gasoline build.
What pipe sizes and accuracy classes fit a retail fuel skid?+
DN15 to DN50 covers retail dispenser feed lines and fleet pump-island manifolds. DN65 to DN100 covers terminal-loading rack arms and aviation refueling truck connections. +/- 0.5% of rate supports retail fuel-sales billing (verify local jurisdiction at order). Commercial fleet-card and aviation refueling that need tighter invoice tolerance step up to Coriolis.
Why is Ex d hazardous-area certification mandatory for gasoline?+
Gasoline is a Class IB flammable liquid (flash point below 23 °C) and forms ignitable vapour at all normal handling temperatures. Retail fuel dispenser zones classify as Zone 1 worldwide, requiring flameproof or intrinsically safe equipment. The LWGY ships with CNEX Ex d IIC T6 Gb for Class IB / Zone 1 service across petroleum, aviation, and fleet refueling.
How does pulse output integrate with fleet card readers and dispensers?+
The 3-wire pulse output is frequency-proportional to flow with the calibrated K-factor on each meter’s certificate. Most fleet-card and dispenser controllers accept the K-factor at programming time and convert pulses to liters or gallons on the receipt printout. RS-485 Modbus and HART are also available.
What is the lead time and what certifications ship standard?+
Lead time is 5–7 business days from order confirmation, factory direct. Each meter ships with an ISO 9001 calibration certificate listing K-factor, calibrated DN, and tested flow range. CNEX Ex d IIC T6 Gb ships standard for gasoline service. EMC 2014/30/EU and IP65 / IP66 / IP67 are selectable. JB/T9246-2016 is the underlying standard.
