Disc meters

Mechanical precision for dispensing hydrocarbons and lubricants

GESPASA MG-80 / MG-80A disc meters represent robust, reliable and autonomous solutions for volumetric fuel measurement.

GESPASA MG-80 / MG-80A disc meters are mechanical oscillating-disc meters, ideal for installations where no electrical power supply is available or where maximum operational simplicity is required.

The MG 84A, MG 80A and MG 80 models have been designed for environments where accurate traceability is required without relying on complex electronics, providing a clear, consistent and durable mechanical readout.

Based on oscillating-disc technology, these units provide an accurate record of the transferred volume by means of an internal positive-displacement system. This technology has historically been valued for its ability to maintain accuracy even when working with variable flow rates or non-constant pressures, ensuring stable measurement under real operating conditions.

One of the key advantages of these meters is their independence from an electrical power supply. Thanks to their direct-reading mechanical indicator, which includes a resettable counter and totaliser, MG models can be installed on mobile tanks, stand-alone fuel dispensers, service trailers or mobile workshops, where electronic systems are not always available. This feature makes them a versatile tool for reliable and simple fuel consumption control.

The bodies of these meters are designed to withstand continuous contact with diesel fuel, kerosene and other petroleum products. Their structural robustness enables use in demanding environments such as transport fleets, construction machinery, agricultural installations or internal refuelling points, where a low-maintenance solution with a long service life is required.

The MG 80 and MG84A stand out for their compatibility with medium flow rates and for incorporating a higher-visibility counter, ideal for fixed or semi-mobile installations. Finally, the MG 80, a version manufactured entirely in plastic, is compatible with a wide range of fluids, including corrosive liquids.
In addition, all models are compatible with GESPASA accessories such as filters, self-priming pumps or quick couplings, enabling direct integration into complete transfer solutions.

Thanks to their modular design, they can be combined with external digital pulse transmitters, converting them into electronic meters without altering their baseline mechanical accuracy. In sectors where fuel control is critical, whether for economic, logistical or regulatory reasons, GESPASA disc meters are established as a reliable, durable and completely self-contained solution.

MG 84A disc meter

MG 84A: clear readout for precise mechanical fuel measurement

The MG 84A disc meter is a mechanical oscillating-disc meter manufactured by GESPASA, ideal for volumetric measurement in refuelling installations, mobile stations or transfer systems.

Its robust and reliable design enables effective control of the fuel dispensed.
High accuracy: ±1% standard / ±0.5% in the optimum range
Rugged construction: aluminium and flameproof chamber
Indicators: resettable (4 digits) + totaliser (8 digits)
Variant with Viton seals (MG-84AV) for demanding liquids

The MG 84A is the most advanced disc meter in GESPASA’s mechanical range. Designed to provide accurate measurement of fuels such as diesel fuel or kerosene, this model stands out for its rugged construction, high readout visibility and operational reliability even under variable flow or pressure conditions.

Its operating principle is based on an oscillating-disc system, allowing it to measure accurately the displaced volume of the fluid without relying on electronic systems. Thanks to this positive-displacement technology, the MG 84A ensures minimal error tolerance and excellent stability in demanding environments. It is ideal for fixed refuelling installations, industrial fuel dispensers or private tanks that require traceability and consumption control without complications.

This model features a large mechanical counter, with a resettable indicator and total accumulated readout, making it easier for the operator to obtain a fast and clear reading of the data, even in low-light environments or from some distance.

The meter body is manufactured in aluminium, enabling continuous use with petroleum derivatives without deterioration of the internal components. In addition, its compact and modular design allows integration into existing or new pumping systems without the need for major technical modifications.

For its reliability, readout clarity and durability, the MG 84A is an ideal solution for those seeking accurate mechanical control, ruggedness and no complex electronic dependencies.

MG 80A disc meter

The GESPASA MG 80A disc meter is a disc-type volumetric meter designed to combine measurement accuracy with a more compact and lightweight format, ideal for mobile installations, portable tanks or refuelling areas with limited space. Thanks to its oscillating-disc system, it provides a continuous flow with excellent fidelity, even under intermittent use or variable flow conditions.

Its purely mechanical operation enables work without an electrical power supply, and the readout is provided by a clearly visible integrated resettable counter and totaliser.

The MG 80A disc meter is built in aluminium, ensuring durability against continuous contact with diesel fuels or light oils. Its rugged design makes it particularly suitable for mobile workshops, maintenance fleets or installations where mechanical reliability is a priority.

Despite its reduced size, it maintains a very low error tolerance, suitable for professional use where fuel traceability is required. It can be used independently or as part of a complete transfer system, together with self-priming pumps, filters and delivery hoses.
