Blue White Industries Flow Meters and Macnaught Flow Meters: Precision Oval Gear Fuel Trackers

Quick Answer: Blue White Industries flow meters and Macnaught flow meters are reliable oval gear fuel trackers for diesel, biodiesel, light crude, and hydraulic oil. For industrial buyers in Southeast Asia, Oceania, Latin America, Africa, and the Middle East, Silver Automation Instruments supplies an equivalent oval gear meter range with pulse, 4-20 mA, and 4-20 mA HART output.

How Blue White Industries and Macnaught Fuel Trackers Work

Blue White Industries is a US manufacturer with a strong position in chemical feed and fluid handling. Macnaught is an Australian brand known for oval gear flow meters used in fuel transfer, oil dispensing, and lubrication systems. Both brands use oval gear positive displacement technology. Two oval rotors rotate inside a precision chamber. Each full rotation displaces a fixed volume of liquid. The rotor movement gives a pulse output. The pulse signal is easy to send to a local display, PLC, or fuel management system.

In practice, this matters for diesel generators, boiler fuel lines, and ship fuel transfer. The meter ignores changes in conductivity and density. That is why oval gear meters work better than turbine meters on low flow and high viscosity oil. But they need clean fluid. A Y strainer upstream is not optional.

Typical Applications We See in Export Markets

We have supplied fuel trackers for diesel generator sets in Indonesia, marine fuel lines in Australia, and paint solvent dosing in Vietnam. A paint manufacturer in Vietnam approached us last year. They had a Macnaught meter on a solvent line running at 25 cP and 3 bar. The imported replacement lead time was 9 weeks. We supplied a stainless steel oval gear meter with PTFE seals and pulse output. The meter has run for 14 months without drift.

In the Middle East, we see oval gear meters on light crude and diesel day tanks. In Africa, mining companies use them on mobile fuel bowsers. In Latin America, food oil processors use oval gear meters with 316 stainless steel bodies and EPDM seals. Most engineers skip the compatibility check. Always confirm the seal material against biodiesel blends and aromatic solvents.

Silver Automation Instruments Oval Gear Fuel Meter Range

Silver Automation Instruments builds oval gear flow meters from DN4 to DN80. The small sizes cover 0.5 to 500 L/h. The larger sizes handle up to 60,000 L/h. Standard outputs are pulse, 4-20 mA, and 4-20 mA HART. We offer local LCD displays, batch controllers, and remote totalizers. For hazardous areas, we can supply ATEX Zone 1 and Zone 2 versions. Materials include cast iron, aluminum, and 316 stainless steel. Seal options include Viton, PTFE, and EPDM.

These meters cover diesel fuel, biodiesel blends, light crude, solvents, hydraulic oil, and food oils. We test every meter with a positive displacement calibration rig before shipment. A calibration report is included with each order. For batch control, we can add a PT100 temperature input to the totalizer. The factory also builds Coriolis mass flow meters, electromagnetic flow meters, ultrasonic flow meters, and vortex flow meters for water, chemical, and gas lines. For water and wastewater lines, our electromagnetic flow meters require a minimum conductivity of 5 µS/cm. If you need a seawater flow meter for a desalination plant, ask our team for a separate selection.

Price, Lead Time, and Spare Parts Reality

Here is the thing. Imported Blue White Industries flow meters and Macnaught flow meters often carry high freight and long customs clearance for buyers outside the US and Australia. Some customers ask us for a direct replacement quote. Our factory can match BSP, NPT, and ANSI flange conn
