Flowmeter Tokico Units: Heavy Industrial Rotary Vane Fuel and Petroleum Counters

Quick Answer: Tokico rotary vane flowmeter units meter fuel oil, diesel, gasoline, jet fuel, and heavy petroleum products by positive displacement. Silver Automation Instruments supplies compatible heavy industrial rotary vane fuel and petroleum counters with mechanical registers, pulse outputs, or 4 to 20 mA HART signals. Send your flow range, pipe size DN, fuel type, and pressure to get a quote within 24 hours.

What Are Tokico Rotary Vane Flowmeter Units

Tokico rotary vane units belong to the positive displacement flowmeter family. A rotor with sliding vanes sits inside a measuring chamber. Each rotation traps a fixed volume of fuel. The counter totalizes that volume. Most engineers specify these units for batch loading, custody transfer, fuel consumption checks, or generator fuel monitoring.

Common sizes cover DN25, DN40, DN50, DN80, and DN100 pipe connections. Flow rates span 6 to 600 liters per minute depending on the meter size. Accuracy for diesel and gasoline is normally plus or minus 0.2 percent. Heavy fuel oil at higher viscosity may run plus or minus 0.5 percent. Repeatability is usually within 0.05 percent.

Heavy Industrial Applications for Fuel and Petroleum Counters

We have seen these counters on many customer sites in Southeast Asia, the Middle East, and Australia. A fuel depot in Surabaya uses rotary vane counters on diesel loading racks. A marine fuel supplier in Singapore meters bunker fuel transfers. A mining contractor in Western Australia counts diesel consumption for gensets and haul trucks. A lubricant blender in Jebel Ali batches base oils through DN50 rotary vane units.

In practice, the installation is simple. Keep the meter full of liquid. Mount a strainer upstream. Add an air eliminator if the fuel aerates. For heavy fuel oil, insulate the lines or keep the temperature above the pour point. Use a water separator on diesel tanks where condensation is common.

Why Silver Automation Instruments Supplies Compatible Tokico Rotary Vane Units

Silver Automation Instruments is a flow meter manufacturer and supplier. We provide heavy industrial rotary vane fuel and petroleum counters that match common Tokico mounting dimensions and process connections. The product range includes aluminum bodies for light fuels and cast iron or steel bodies for heavy oils. Seals are available in Viton or PTFE. Bearings can be selected for gasoline, diesel, biodiesel, kerosene, or heavy residual fuel oil.

Output options include a mechanical register, a pulse transmitter, or a 4 to 20 mA HART signal. For hazardous areas, we can supply units rated for ATEX Zone 1 or Zone 2. We do not sell OEM Tokico branded meters as a distributor. We supply compatible replacements with the same flange patterns and similar performance.

Here is the practical point. If your Tokico meter is obsolete or the delivery time is too long, a compatible Silver Instruments unit can often drop into the same pipe run without changing the flanges or the batch controller.

Sizing Data You Need for a Quote

Most engineers skip this part and later face delays. Send these details in the first inquiry. Fuel type matters because viscosity and lubrication change the meter selection. Diesel, gasoline, aviation fuel, heavy fuel oil, and crude oil all behave differently. State the viscosity in centipoise or centistokes if you know it.

A typical inquiry should include pipe size DN, flow range in liters per minute or cubic meters per hour, operating pressure in bar, operating temperature in degrees Celsius, process connection type, and required output. Also state if the meter needs a mechanical totalizer, pulse output, or 4 to 20 mA HART output.

Last year a customer in Vietnam needed twelve rotary vane fuel counters for a diesel loading skid. H
