The Fox Power Pro™ Sensor
, available on Models FT2A and FT3, offers higher accuracy and a wide turndown ratio of 1000:1 (100:1 typical). It can operate in velocities up to 60,000 SFPM – almost twice that of competitors units – while still performing accurately in very low flow applications.
The Fox DDC-Sensor™
, available on Models FT1, FT4A, and FT4X, is a Direct Digitally Controlled sensor that interfaces directly with the microprocessor to allow more speed and programmability. It also provides a technology platform for calculating accurate gas correlations.
gas selection menu available on Model FT1, with an expanded selection available on the FT4A
, uses a correlation algorithm from one calibration to allow the meter to measure multiple pure gases and gas mixtures.
Models FT1, FT3, FT4A, and FT4X offer an in-situ Calibration Validation feature. This feature allows the operator to confirm that the meter is running accurately in the field, without the need to send the meter back for annual factory calibrations. Calibration Validation Certificates can be printed if the free FT View software is used to initiate the tests. This feature is of particular value in environmental monitoring applications where periodic calibration verification is mandated.
The Model FT4X offers an advanced data logger for use in oil & gas applications. It includes 40 daily totals (24-hour totals), settable Contract Time to define the Contract Day, time/date stamped alarm/event logs, a 7-year history, and a power off totalizer.
