Fox Thermal Instruments' Model FT3’s CAL-V feature is an in-situ calibration validation routine that validates the flowmeter’s calibration accuracy. This innovative approach lets you validate instrument calibration in the pipe, at your process conditions, with just the push of a button. CAL-V can be used to streamline your quality assurance initiatives, improve process efficiency and apply scheduled maintenance procedures. It is of particular value in environmental monitoring applications where periodic validation is mandated. Other advanced features of the FT3 are HART or RS485 Modbus Communication Options and the free FT3 View Software Tool.
