SITRANS F US ultrasonic flowmeters are used with homogenous conductive and non-conductive liquids. In addition to standard volume flow, ultrasonic flowmeters can provide information on media quality and temperature. Meter calibration can be certified to industry standards.

Siemens Controlotron’s Clamp-On Transit-Time Ultrasonic Flowmeters have been field installed in critical applications globally since the early 1970’s. Experience, reliability, and innovative use of technology set our products apart. Patented Wide-Beam™ Transit-Time and Reflexor™ technologies assure accurate reading even in difficult applications. Being non-intrusive is the key to universal applicability to all industries.

The Highly Reliable 1010 Product Family Features:

• Accurate flow measurement regardless of liquid type or temperature
• Operation with up to 50% aeration and indication of aeration presence
• Resistance to Aberrated Flow Profile and Crossflow errors
• Continuous Automatic Zero adjustment to prevent Zero drift
• Full installation without cutting pipeline or stopping flow
• Sonic identification of product type and quality
• Conventional digital and analog data outputs
• Direct interchangeability with conventional intrusive flowmeters
• Excellent cost efficiency

The differences between Siemens Controlotron and other competitive ultrasonic instruments are substantial. One component of the reason for this is the large number of Patents owned and used by Siemens Controlotron.

Other ultrasonic flowmeters use transducers with fixed frequencies, which experience cancellation as they transmit through the pipe wall of a mismatched frequency. Since the pipe wall acts as an obstacle to the beam, insert type flowmeters are popular as the beams are transmitted without passing through the pipe wall. However, insert type sensors require many paths as the beams are small and sample a small percentage of flow volume. Insert type sensors are also inline type, requiring downtime.

Siemens Controlotron’s Wide Beam has the following advantages:

• Matches transducer frequency to pipe, transforms pipe into sensor
• Low Voltage (+/- 15V) vs. 300+V in others
• Application Diagnostics & Tolerance – senses pipe build-up, up to 50% aeration in liquids, moisture or wet gas, hydrate detection
• Pico-seconds time resolution – allows measurement of lower flows and smaller pipes
• No Pressure Drop or Energy Loss (non-intrusive)
• Larger path volume sampling = fewer paths & less cost required
• Continuous auto-zeroing function ensures zero stability

The SITRANS FUS060 is a high performance, easy to mount transmitter developed for rugged industries within oil, petrochemicals, power plants or water and wastewater. It is especially suitable for applications that demand accuracy, custody transfer approvals and bus communication.

SITRANS FUE380

The easy-to-use, stand-alone digital ultrasonic pipe wall thickness gauge is an indispensable tool in accurate clamp-on ultrasonic flow measurement. Since even the smallest miscalculation of the pipe wall thickness can have a major impact on a clamp-on flowmeter's accuracy, the pipe thickness gauge has to be extremely precise. This is why the standard probe operates at a 5 MHz frequency enabling it to measure even the smallest pipe thickness. Although the thickness gauge was originally designed to increase the accuracy of clamp-on flowmeters, it can be used to measure the thickness of any pipe wall.
