Tronair H-1416 Flowmeter Assembly

The Tronair H-1416 Flowmeter measures and displays the volume of fluid flowing through compatible Tronair aircraft lavatory carts. It provides accurate tracking of fluid transfer during servicing operations, helping ground crews monitor usage and maintain proper cart performance. By delivering consistent measurements, it supports operational efficiency and service accountability. It plays a key role in ensuring aircraft lavatory servicing is performed accurately and safely.

The H-1416 Flowmeter Assembly is a direct replacement part for the flowmeter on specific Tronair aircraft lavatory service units, including models 10-6411-0000, 10-6401-0010, and 10-6402-0010. It is engineered to integrate directly into these units without modification. Other applications may also be possible depending on equipment configuration. Contact our aviation specialists to confirm compatibility with your specific lavatory cart.

The Tronair H-1416 Flowmeter utilizes a nutating disc mechanical flowmeter design. This design uses internal gears and a measuring chamber to convert fluid movement into mechanical counter readings. Nutating disc meters are known for durability and consistent accuracy in medium-flow applications. This makes the H-1416 well-suited for ground support equipment such as aircraft lavatory carts.

The H-1416 Flowmeter operates within a recommended flow range of approximately 5 to 20 gallons per minute (GPM) or 19 to 76 liters per minute (LPM). This range aligns well with the typical output of lavatory service equipment. Operating within this range helps maintain optimal measurement accuracy and prolong the longevity of internal components. Exceeding recommended flow rates may impact performance.

The Tronair H-1416 Flowmeter offers approximately ±1% accuracy under proper operating conditions. Accuracy depends on proper installation, calibration, and maintaining a fluid flow free of air. Periodic calibration helps ensure continued precision. This level of accuracy is important for maintaining reliable service records and fluid accountability.

The maximum working pressure for the H-1416 Flowmeter Assembly is 50 PSI (3.5 bar). Operating within this pressure limit helps prevent damage to the meter housing and internal components. Proper system design and pressure regulation are important for safe, long-term use. Exceeding pressure limits may result in component failure or cracking.

Yes, the Tronair H-1416 Flowmeter can be calibrated to ensure accurate measurements. Calibration is typically required after disassembly, significant wear, or when measuring different fluids. The process involves using a container of known volume and adjusting the internal calibration screw. Proper calibration helps maintain measurement accuracy over time.

Yes, the Tronair H-1416 Flowmeter features a resettable mechanical counter with large, easy-to-read numbers. The reset knob allows operators to return the display to zero before beginning a new transfer. It also includes a totalizer that records cumulative volume over time. This combination supports both per-service measurement and long-term tracking.

The H-1416 Flowmeter is designed for minimal maintenance under normal operating conditions. However, certain fluids may dry inside the meter and require cleaning. Routine flushing and occasional inspection help prevent buildup and ensure continued accuracy. If internal components wear or become damaged, repair kits are available for servicing.
