Great Plains Flow Meter Catalog: Electronic and Mechanical Fuel Transfer Instrumentation Kits
Quick Answer: The Great Plains flow meter catalog for electronic and mechanical fuel transfer instrumentation kits covers small and mid size fuel skids, truck unloading, and diesel delivery. Silver Instruments supplies direct replacement oval gear meters with pulse, 4-20 mA HART, or mechanical register output. Send the fuel type, pipe size, and flow range to get a cross reference within one working day.
For a direct quote, send fuel type, pressure in bar, temperature in °C, pipe size in DN, and flow range. Contact Silver Automation Instruments at Tel: +86-25-68650347, Whatsapp: +86-25-52155837, or WeChat: +86 15365082610.
Mechanical Fuel Transfer Kits and Local Register Options
A mechanical kit from the Great Plains flow meter catalog often includes an aluminum or cast iron meter body, a local register, a strainer, and an air eliminator. Silver Instruments supplies a similar oval gear meter in aluminum for diesel and light oil. The standard offering covers DN15 to DN50 lines, 10 to 300 L/min, and pressures up to 20 bar. Temperature range is -20 °C to 80 °C for standard Viton seals. For fuel oil at 120 °C, PTFE seals are available.
For heavy fuel oil at 80 to 120 °C, the meter seals need to be Viton or PTFE. A PT100 probe can be added to correct volume to 15 °C when the fuel temperature moves outside 10 to 30 °C. Most diesel transfer skids do not need temperature compensation. It becomes useful when the batch temperature changes by more than 15 °C between morning and noon.
In practice, a mechanical register works well when the operator fills a tank and writes down the batch volume. A paint manufacturer in Southeast Asia replaced a broken mechanical register with a Silver Instruments aluminum oval gear meter last year. The line size was DN25 and the flow range was 15 to 80 L/min. The customer sent a photo of the old nameplate and we matched the flange pattern within two days.
Most engineers skip the air eliminator on first install. That is a mistake. Air bubbles cause the oval gear meter to overregister and the pulse output to count volume that is not fuel. Install a simple air release valve after the pump and before the meter.
Electronic Fuel Transfer Kits with Pulse and 4-20 mA HART
Electronic kits use a pulse output from the meter head. The output can feed a local batch controller, a PLC, or a remote display. Silver Instruments offers a reed switch pulse with 0.1 L per pulse or a Hall effect sensor with 10 to 1000 pulses per liter depending on the meter size. For longer cable runs, a 4-20 mA HART output is simpler because it carries flow rate and totalizer data on one pair of wires.
A customer in the Middle East ordered 12 electronic fuel transfer kits for a temporary power plant. Each skid used a DN40 oval gear meter with a 4-20 mA HART output and an ATEX Zone 2 rating. The fuel was diesel at 15 to 25 °C and the flow range was 30 to 150 L/min. The site team needed no local display because the control room pulled data through a HART multiplexer.
For additive injection or custody transfer batching, a Coriolis mass flow meter gives mass flow in kg/h and density in kg/m³. Silver Instruments can supply a Coriolis meter with 4-20 mA HART and Modbus RTU. This option fits fuel termina
Cross Reference from the Great Plains Flow Meter Catalog
Many buyers ask for a direct cross reference from a Great Plains electronic or mechanical fuel transfer instrumentation kit. The key points are not only the brand code. You need to confirm the flow range, connection type, seal material, and output. A typical cross reference request includes fuel type, pressure in bar, temperature in °C, pipe size in DN, and required signal output.
Silver Instruments does not use the exact Great Plains part number. We match the meter body size, thread or flange standard, flow range, and output. For example, a 1 inch NPT aluminum fuel meter with pulse output can be matched by a Silver Instruments DN25 oval gear meter with BSP or NPT threads. The pulse scaling is set at the factory to the nearest 0.1 L per pulse.
Which Meter Works for Diesel, Biodiesel, and Kerosene
Diesel and kerosene have low viscosity, usually 2 to 6 cP at 20 °C. Biodiesel blends up to B20 stay close to 5 to 7 cP. A positive displacement oval gear meter handles these ranges well. A turbine meter also works but can overread when air bubbles pass through the line. For fuels with viscosity below 1 cP, like some solvents, a Coriolis mass flow meter is more stable.
Water in fuel causes corrosion and register failure. Install a 40 mesh strainer before the meter and a water separator after the pump. Silver Instruments aluminum meters have an optional epoxy coated chamber for wet fuel service. For marine diesel with high humidity, we recommend the stainless steel chamber version. For sites that handle diesel with possible free water, a water in fuel sensor with µS/cm output can stop the pump before the meter sees a slug of water.
FAQ on Fuel Transfer Meter Kits
What flow range do the electronic and mechanical fuel transfer kits cover?
Silver Instruments standard oval gear fuel meters cover 4 to 300 L/min. Larger line sizes up to DN100 can handle 600 L/min for terminal loading. Send the pump capacity and pipe size to confirm the correct meter size.
Can the Silver Instruments meter replace a Great Plains mechanical register directly?
In most cases yes. You need to confirm thread size, flange pattern, flow direction, and register orientation. The meter body length may differ by 5 to 15 mm. We provide dimension drawings before shipment.
What output is best for a PLC on a fuel skid?
A pulse output is the lowest cost option for a local PLC. Use 4-20 mA HART if the cable length is over 50 m or if the site requires remote diagnostics. Both outputs are available on Silver Instruments electronic fuel meter kits.
Do the meters have hazardous area approval for fuel transfer?
Silver Instruments can supply optional ATEX Zone 1 and Zone 2 versions. Intrinsically safe pulse and 4-20 mA HART outputs are available. The mechanical register version does not need power and is suitable for Zone 2 when selected with aluminum or stainless body.
What details should I send for a price and cross reference?
Send the fuel type, flow range in L/min or kg/h, pressure in bar, temperature in °C, pipe size in DN, thread or flange standard, and required output. For urgent quotes use Tel: +86-25-68650347 or Whatsapp: +86-25-52155837.
