Accurate fuel unloading measurement for tanker trucks, gas stations, fuel depots, and mobile fuel transfer operations.
The HMZ TM-80(E) Bluetooth Portable Gravity Unloading Flowmeter is designed for accurate measurement during gravity-based fuel unloading. It is commonly used when gasoline, diesel, kerosene, or ethanol gasoline is discharged from a tanker truck into a storage tank, gas station underground tank, or fuel receiving system.
With a flow range of 8–80 m³/h, accuracy of ±0.2%, Bluetooth data transmission, IP67 protection, and multiple quick connector options, the TM-80(E) helps operators verify delivered fuel volume, reduce manual recording errors, and improve unloading data management.

The TM-80(E) is used to measure fuel volume during gravity unloading from tanker trucks. It is especially suitable for fuel receiving operations where the fuel flows naturally from the tanker outlet into a storage tank without a dispensing pump.
Typical applications include:
The TM-80(E) provides ±0.2% accuracy, helping operators verify the actual quantity of fuel received during tanker unloading. This is useful for reducing disputes between fuel suppliers, transport companies, and fuel station operators.
The Bluetooth-enabled metering system allows unloading records to be exported for data management and operation tracking. This helps replace handwritten unloading records with more convenient digital records.
The flowmeter is compact and portable, making it suitable for mobile unloading operations, temporary fuel receiving points, tanker truck service teams, and fuel stations that need flexible measurement equipment.
The TM-80(E) can be used for:
It is designed for fuel and oil unloading applications, not for water measurement.
Different unloading sites and tanker truck outlets may use different connection sizes. The TM-80(E) can be supplied with quick connector options including:
Connector configuration can be confirmed before production according to the customer’s tanker outlet and unloading hose requirements.
With IP67 protection grade, the TM-80(E) is suitable for demanding fuel unloading environments where dust, splash, and outdoor working conditions may be present.
The TM-80(E) has the explosion-proof sign:
Ex ia IIB T4 Ga
This makes it suitable for fuel-related working environments where explosion-proof equipment requirements must be considered. Final application should always follow local safety regulations and project certification requirements.

The TM-80(E) is connected between the tanker truck discharge outlet and the unloading hose or receiving pipeline. During gravity unloading, fuel flows through the turbine metering chamber. The built-in electronic metering system calculates the fuel volume and displays the unloading data.
For digital management, Bluetooth transmission allows operators to export or manage unloading records, depending on the configured software and device version.
For best measurement performance, the flowmeter should be installed according to the unloading direction and pipe connection requirements.
