Space Saving Design

em-tec’s flow meter design allows you to save space and achieve greater accuracy in flow measurement with a non-invasive method. It is extremely compact due to a highly integrated digital electronic design.

Overview

The em-tec flow sensor comes pre-calibrated for the user, requires no priming, and contains the ability to use 7 different calibration tables – all on one sensor. The BioProTT transducer, with transit-time technology, provides simple, clamp-on flow measurement of tubing systems. The transducer quickly and easily clamps around flexible hoses with a click lock. This lock ensures that contamination and pressure-drops within the system will be avoided, as well as no extra assembly splicing.

The functional design of this em-tec flow meter features no moving parts and prevents any additional shearing on the process fluid, giving it a great advantage over invasive methods that also handle biomolecules or shear-sensitive organisms.
