Flow Transfer Standard Continuous Loop Calibrator
The Flow Transfer Standard Continuous Loop Calibrator (FTS–CL) is used for calibrating meters that do not require a Primary Standard Calibrator uncertainties of ±0.05%. The FTS–CL will obtain uncertainties of ±0.15% which is acceptable for meters that require ±0.5% of reading calibration accuracy. Typical meters ran on this type of calibrator are rotameters and water meters used in less precision applications. Users are OEM commercial meter manufacturers, government calibration labs, FFA repair centers, etc.
The main purpose of the FTS–CL Calibrator is to perform
accurate liquid flow calibrations on various types of flowmeters.

The Flow Transfer Standard–Continuous Loop Flow Calibrator system is a bench–type, self–contained calibrator. The heart of the calibrator is a precision and highly repeatable dual–rotor turbine flow meter manifold system. When properly sized, the FTS–CL will produce uncertainties of ±0.15%. The FTS–CL system consists of a minimum two dual–rotor turbine flow meters with flow conditioners in a manifold configuration, three positive displacement pumps with clutch and motor speed controller, and electronic interface module and a personal computer with Flow Dynamics' Flo–Cal software. The calibrator provides an adjustable test section for units under test as well as a fluid reservoir and fluid filters incorporating a continuous flow loop calibrator system.
The data acquisition system records important flow calibration data and provides a means for maintaining historical flow meter calibration data. The operator may record data, prepare graphics, and perform calibrations on various types of liquid flow meters.
