Overview
Accurate, hygienic and contactless flow measurement. The IFS ultrasonic flow sensor measures flow precisely and ensures exact metering in the application. Evaluation electronics perform measurement evaluation in real time and powerful processor technology enables fast and precise measurement.

Key features

• AVS Römer push-in connector with patented hyperfit® technology
• Evaluation electronics for measurement evaluation in real time
• Ultrasonic sensors for contactless measurement
• Dead-space optimized hygienic design
• Free pipe cross-section enabling full flow
• Integrated temperature compensation for precise measurement

Advantages

• Hygienic design: contactless measurement, dead-space optimized, patented hyperfit® sealing concept
• Fast and precise measurement: powerful processor technology and real-time measurement evaluation
• Top performance: free pipe cross-section for full flow and precise measurement due to integrated temperature compensation
• Wide range of applications: water, milk, syrup and others on request

Functional principle
The ultrasonic flow measurement is performed according to the flow time difference method. Mean flow velocity v_m is derived from the transit time difference between sensors. Formula (text): v_m = (c^2 / (2 * L)) * (1/t1 - 1/t2). Where v_m = mean flow velocity, c = sound velocity, L = length of the measuring distance between the sensors, t1 = time from sensor 1 to sensor 2, t2 = time from sensor 2 to sensor 1. The mean flow velocity and the flow cross-section A give the flow rate Q: Q = v_m * A.
