The 3244-1.5” is designed for fuel dispensing systems that require a larger connection and a higher maximum flow rate than the 1-inch version. Its four-piston positive displacement mechanism, rotary valve, and adjustable measuring system support dependable mechanical fuel measurement, while the aluminum body and double oil seals contribute to a durable design.
For fuel equipment distributors and system integrators, the 1.5-inch connection and flow range of 12–150 L/min make this model an option for compatible higher-capacity fuel transfer and dispensing systems.
The 3244-1.5” is worth considering when the system requires a 1.5-inch connection or a flow capacity of up to 150 L/min. The 1-inch model has a listed flow range of 12–100 L/min. The appropriate choice depends on the system’s required flow rate, pipework, and equipment configuration.
The mechanism measures liquid through defined displacement cycles, providing a practical approach to mechanical fuel metering. The rotary valve and external adjustment mechanism support measurement consistency and calibration for compatible fuel dispensing applications.
The listed applicable fluids include biodiesel, diesel, HVO, XTL, gasoline, and kerosene. The suitability of the meter depends on the fluid’s properties and compatibility with the meter’s sealing materials and operating conditions.
The 1.5-inch inlet/outlet is an important consideration when matching the meter to the fuel system’s pipework and target flow rate. Buyers should evaluate connection compatibility, required flow, and the system’s working pressure when selecting the meter for new or existing equipment.
Distributors should evaluate the target fuel, operating flow range, connection size, pressure requirements, accuracy requirements, and installation dimensions. The 3244-1.5” offers a listed flow range of 12–150 L/min, ±0.2% accuracy, and a 3.5-bar working pressure specification for equipment selection and system planning.
This RSJ50 flow meter with filter adopts advanced technology of U.S. Bennett company, which can be widely used for different fuel dispensers. With advantage of high flow, long working life, high accuracy, firm structure, easy installation, etc., it can be the best choice of fuel dispenser component.
