3 PRODUCT DESCRIPTION
3.3 Product features and functions
3.3.1 Principle of operation
The DOSIC
®
measures flow volume using ultrasonic technology and the time-of-flight
method, making the sensor suitable for measuring both conductive and non-conductive
liquids.
The sensor has two configurable digital inputs and outputs and up to two analog out -
puts. The switching output (Q1) also features an IO-Link interface; see “7.2.3 IO-Link”.
3.3.2 Fields of application
With its measurement channel and stainless-steel housing, the ultrasonic flowmeter is
suitable for measuring tasks in hygienic environments. The compact and rugged design
makes the sensor ideal for a wide range of applications, including those where space
restrictions or aggressive media play a role.
Installation is quick and easy, and does not require medium calibration. The seal-free,
self-draining measuring channel enhances process reliability. The straight shape of the
measuring channel reduces pressure loss, which in turn reduces energy costs.
The DOSIC
®
is EHEDG-certified, and all materials that come into contact with the media
are FDA-compliant.
This makes the DOSIC
®
suitable for use in applications such as:
− The food industry
− CIP/SIP systems
− Filter systems
− Osmosis systems
− Measurements with high-purity water
NOTE
Due the ultrasonic technology used is always recommended to perform evaluation tests
on media that differ from water. To perform a first evaluation test it is enough to fill the
channel of the sensor and close the two process connections of the sensor with blind
plugs. Should the sensor show zero flow without any error message there is a good
probability that the medium can be measured. In any case a test in the final installa -
tion conditions provides the definitive answer if the DOSIC
®
can measure the specific
medium.
