Ultrasonic Flow Meter

Description

ASIONIC™ 200 CF Clamp-On Ultrasonic Flow Meters are designed for accurate flow measurement of liquids in industrial applications. Since the sensors are clamped directly onto the outer surface of the pipe, the system eliminates all process compatibility issues associated with in-line flow meters.

The flow meter operates on Transit Time Measurement Technology, where ultrasonic signals are sent with and against the flow direction. By comparing the travel times, the system accurately calculates fluid velocity and volumetric flow rate. Sonic properties of the pipe and fluid are factored in, ensuring highly repeatable accuracy.

ASIONIC™ 200 CF is ideal for users requiring a non-intrusive, easy-to-install solution that maintains precise flow measurement for clean liquids — especially in applications where:

• In-line meters were not previously installed,

• Large pipe diameters exist, or

• Pipe materials are exotic or incompatible with in-line technologies.

The clamp-on design allows installation without stopping the flow or cutting the pipeline, making it suitable for both retrofits and new process setups.

Description

ASIONIC 200 CF-B Battery Powered Clamp-On Ultrasonic Flow Meters are designed for accurate flow measurement of clean, sonically conductive liquids in industrial applications. Since the sensors are clamped externally on the pipe, the system eliminates any risk related to process compatibility commonly associated with in-line flow metering technologies.

The meter operates on the transit time measurement principle, where the instrument calculates fluid velocity by comparing the travel time of an ultrasonic signal moving with the flow versus a signal moving against the flow. By incorporating the sonic characteristics of the fluid and the pipe material, the system delivers highly repeatable and reliable volumetric flow measurements.

ASIONIC 200 CF-B is ideal for applications where easy installation, no process interruption, and zero pipeline modification are required. It is particularly suitable for large line sizes and installations where the use of exotic materials makes in-line metering uneconomical.

ASIONIC™ 200C Clamp-On Ultrasonic Flow Meters accurately measure liquid flow rates in industrial applications without any pipe cutting or process interruption. Since sensors are clamped externally onto the pipe, the system eliminates contamination, pressure drop, maintenance issues, and material compatibility concerns associated with inline flow meters.

The meter uses Transit Time Technology, comparing the travel time of ultrasonic signals moving with and against the flow. This enables accurate and repeatable measurement of fluid velocity and volumetric flow rate while accounting for sonic properties of the pipe and fluid.

ASIONIC™ 200C supports one or two transducer inputs, allowing comparison between two flow streams. It is ideal for applications requiring non-intrusive installation, measurement on large-diameter pipes, or pipelines made from special materials where inline meters are impractical.
