Description

The FDT-30 series has been discontinued. Please see the FDT-40 as a possible alternative or contact our Flow Engineering department.

The FDT-30 Series provides easy and low cost installation by clamping to the outside of existing piping systems. Non-invasive transit time system allows solids to pass through the pipe with no affect on the meter. Y-strainers or filtering devices are not needed. Greater accuracy can be attained in applications consisting of entrained gases. The FDT-30 Series will automatically correct displayed flow rates and electronic outputs. Direct interface is provided to data collection systems via 4 to 20 mA output and either TTL-pulse or simulated turbine meter outputs that are proportional to fluid flow rate. Designed to replace mechanical flowmeters in applications where liquid conditions tend to damage or impede mechanical flow meter operation. No maintenance is required. The FDT-30 Series can be used on applications such as well water and other liquids with moderate amounts of suspended solids or aeration.

FDT-30 Series is housed in an enclosure suitable for outdoor mounting. Integral mount transducers are available for pipes 50 mm (2") and smaller.
