Installation
Five install rules, with light-fuel-oil specifics on viscosity verification, strainer selection for distillate cuts, and depot-tanker pump-discharge mounting.
- Verify operating viscosity ≤10 cSt; calibrate within ±20% of operating viscosity.
- 200-mesh Y-strainer ≥ 5D upstream; clean every 90 days on depot service.
- Mount horizontal with manual bypass loop for in-service strainer cleaning.
- 10D upstream / 5D downstream; 20D after a 90° elbow, 50D after a partial-open valve.
- Bench-test pulse pre-install; cable ≤ 1000 m, ground ≤ 10 Ω, 12-month bearing inspection.
Frequently asked questions
Can this meter measure HFO, IFO 380, or IFO 180?+
No. The LWGY turbine is bound to clean low-viscosity liquid only; typically ≤10 cSt at operating temperature. HFO at 50 to 90 °C still runs 30 to 380 cSt, far above the turbine accuracy range; bearing loading and K-factor viscosity-shift make turbine measurement unreliable. For HFO, IFO 380, IFO 180, marine bunker, and other residual fuel service, use Coriolis (mass-flow-based, viscosity-independent) or a positive-displacement meter.
Which fuel oil grades does this model actually cover?+
Light fuel oil grades ≤10 cSt at operating temperature: No. 1 fuel oil (kerosene-grade, ≈1.5 cSt at 40 °C), No. 2 fuel oil (residential heating oil, ≈3 cSt at 40 °C), No. 4 light commercial heating oil (≈5–8 cSt warm), refinery distillate cuts and light cycle oil (≈3–6 cSt warm), and light gas-oil. NOT covered: No. 5 fuel oil, No. 6 / Bunker C, IFO 380, IFO 180; use Coriolis or PD.
What is the difference between this model and the diesel-flow-meter?+
Both run LWGY with 316L body + Ex d zone-1; both cover DN4 to DN300. Diesel model targets EN 590 / ASTM D975 / biodiesel automotive grade; retail dispenser, fleet card-lock, terminal manifold. Light-fuel-oil model targets stationary heating-oil delivery, light-distillate burner feed, kerosene depots, refinery light-distillate movement. Same hardware, different application scenario. If your application fits both, order the diesel cert documentation; group-IIA / IIB cert is broader.
What bore range and flow rate matches each light-fuel-oil service?+
DN4 to DN300 maps to fuel-oil service as follows. Residential #2 heating-oil tanker delivery DN20–DN25 at 1 to 5 m³/h. Commercial heating-oil bulk DN40–DN65 at 5 to 30 m³/h. Burner feed DN50–DN100 at 10 to 100 m³/h. Refinery light-distillate transfer DN80–DN150 at 50 to 300 m³/h. Tank-farm depot DN200–DN300 at 200 to 1800 m³/h. Lab dosing and burner-pilot oil DN4–DN15.
How accurate is the meter for #2 heating-oil delivery custody-transfer?+
Standard ±0.5% across 1:10 to 1:20 turndown. For weights-and-measures-grade tanker delivery, the standard ±0.5% build with a K-factor verified at operating viscosity meets the trade-authority verification interval in most jurisdictions. Refinery custody-transfer and large-volume depot accounting that need tighter tolerance step up to Coriolis (viscosity-independent mass flow). Verify K-factor calibration was performed within ±20% of the operating viscosity.
What output signal pairs with depot SCADA and tanker meter-tickets?+
Depot SCADA (Honeywell Experion, Emerson DeltaV, Yokogawa Centum) runs 4-20 mA + HART. Tanker on-board meter-ticketing systems and pump-discharge controllers accept pulse output for K-factor scaling at the loading-arm head. Refinery DCS (ABB 800xA, Yokogawa, Emerson) runs HART + Modbus dual output. Unattended remote depots: specify GPRS-IoT (code 6). State the SCADA / DCS make at quote.
What is the lead time and what certification ships standard?+
Lead time is 5–7 business days, factory direct. CNEX Ex d IIC T6 zone-1 ships standard for depot, refinery distillate-loop, and burner-room installation. EMC 2014/30/EU (Annex II) ships standard. JB/T9246-2016 calibration certificate with each meter. IP65/66/67 selectable; IP66 typical for outdoor depot manifolds, IP67 for tanker pump-discharge stations exposed to washdown.
