Sound speed sensor / for measuring concentration - SPRn 4214, STR 4214
The SPRn 4214 and STR 4214 are sound velocity sensors developed by Anton Paar. They are specifically designed to measure concentration in small-diameter pipes with low-flow rates online. The sensors provide continuous monitoring of the product quality of liquids in times of production. The calculation, display and process of the concentration may be through an evaluation unit. The calculation may also occur inside the sensor with a 4mA-20mA signal.
