Turbine Flowmeter Suitable For Heavy Equipment

Flow Technology has launched the FT-HE (heavy equipment) turbine flowmeter solution designed for hydraulic fluid applications. The company's FT series turbine meters are now offered with SAE J1453 fittings with O-ring face seal, which is said to simplify installation in hydraulic lines onboard tractors, combines and other heavy equipment. In the off-road industry, there is an increasing emphasis on reducing both the number of potential leakage points and the incidence of leakage from hydraulics systems on machinery.

This requirement is addressed by the SAE J1453 standard covering material, dimensional, and performance requirements of steel O-ring face seal fittings for hydraulic tubing, as well as the O-ring face seal interface and nut portion of hose stem assemblies. The FT-HE solution is said to provide accurate and repeatable flow measurements in a host of hydraulic and pneumatic applications.

Units employing SAE J1453 flat-face male-to-male fittings do not require adapters for use in off-road equipment hydraulic lines. This approach reduces the space required for meter installation and ensures fewer possible leakage points in the hydraulic system. Flow Technology said its FT series turbine flowmeters are an ideal choice when accuracy, compact size and fast response are critical. The meters are suitable for a variety of liquid and gas flow sensing applications.

FT-HE turbine meters are available for up to 1.5in line sizes and are offered in both standard and high-shock (HS) configurations. The SAE J1453 fittings are intended for general applications and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These fittings are capable of providing leak-proof full-flow connections in hydraulic systems operating from 95kPa (28 in Hg) vacuum to working pressures.
