Fuel Injection Air Flow Meter Tuntrol TP003 Aluminum Alloy 7-20 GPM

Description

Product Overview

The Tuntrol TP003 fuel injection air flow meter is engineered to provide accurate, repeatable measurement of liquid flow in a wide variety of automotive and industrial contexts. Built around a solid aluminum alloy housing, the meter combines lightweight strength with resistance to corrosion, ensuring a long service life even when exposed to harsh fuels such as diesel, gasoline, biodiesel, and kerosene. The device features a 1″ NPT threaded inlet and outlet, allowing straightforward integration into existing fuel lines without the need for custom adapters. Its flow range of 7‑20 GPM covers low‑to‑moderate flow rates typical of fuel transfer pumps, while the internal sensor can tolerate pressures up to 50 bar, giving it a safety margin well beyond normal operating conditions.

Precision is at the heart of the TP003 design. The meter offers ±1% accuracy, a level of tolerance that meets the demands of modern engine management systems and emission testing protocols. Users can fine‑tune the instrument by adjusting the internal top‑line workbench after removing a rear screw, a process described in the included manual and designed for quick field calibration. The large‑screen digital display presents a four‑digit subtotal that can be manually reset to zero, and an eight‑digit total that records cumulative flow without reset, enabling both short‑term monitoring and long‑term data collection.

Usage

The TP003 excels in environments where reliable fuel measurement is critical. In automotive service bays, technicians use the meter to verify fuel pump performance, calibrate fuel injectors, and ensure compliance with manufacturer specifications. For fleet operators, the device helps monitor fuel consumption across multiple vehicles, providing data that can be used to optimize routes and reduce operating costs. In biodiesel production facilities, the meter measures the transfer of B20 blends and pure biodiesel, supporting quality control and inventory management. Its compatibility with engine oil and lubricants also makes it a valuable tool for oil change services, where precise volume tracking prevents over‑filling and protects engine components.

Installation is straightforward: attach the NPT threads to the fuel line, secure the gasket or sealing tape to prevent leaks, and verify the connection with a pressure test. A filter should be placed upstream of the meter to protect the internal blades from debris that could cause jamming. Once installed, the user can observe real‑time flow data on the display, reset the subtotal as needed, and rely on the cumulative total for post‑operation analysis. The meter’s compact dimensions—9.33 x 7.64 x 7.01 inches—and weight of 3.61 pounds make it easy to mount in tight engine bays or portable fuel transfer kits.

FAQ

What types of fluids can the TP003 measure?

The TP003 is designed for liquid media including diesel, gasoline, kerosene, mineral spirits, B20 biodiesel blends, E15 ethanol blends, engine oil, and other lubricants commonly used in fuel transfer applications.

How do I calibrate the meter for maximum accuracy?

Calibration is performed by loosening the rear screw, accessing the internal top‑line workbench, and making fine adjustments as described in the user manual. For most users, a simple zero‑reset before each measurement session provides sufficient accuracy; however, periodic professional calibration is recommended for critical applications.

Can the meter be used in high‑pressure fuel systems?

Yes. The TP003 is rated for a maximum working pressure of 50 bar, which exceeds the pressure levels of typical automotive fuel systems, making it safe for use in both standard and high‑performance environments.

What maintenance is required to keep the meter functioning properly?

Regularly inspect the gasket and sealing tape for wear, replace the upstream filter to prevent debris buildup, and verify that the NPT connections remain tight. Cleaning the sensor housing with a compatible solvent will help maintain accuracy over time.

Is the TP003 compatible with electronic fuel injection controllers?

The meter provides a digital readout that can be manually recorded or integrated into data‑logging systems. While it does not output a direct electronic signal, the measured flow values can be entered into engine control software for tuning and diagnostics.
