CLAMP-ON ULTRASONIC METERS The clamp-on mounting style employed by the ultrasonic flowmeter provides a number of advantages over traditional mechanical flow measurement techniques such as excellent longevity low maintenance no pressure loss and.

Flow Meter Meets The Highest Safety Standards Gmptec

What are the two basic principles.

. The Tek-Clamp 1200A operates according to the difference in the Transit Time of Flight measured and determines the flow velocity by measuring the travel time of a pulse from one transducer to the next. Basic Controls clamp for ultrasonic flow meters features the clamp on the installation design. The flowmeter assumes a fully developed flow profile.

The required straight run is depeding on the type of flowmeter. LRF-3000S is high-end clamp-on ultrasonic flow meter. It adopts our self-developed TGA measurement technology.

NameClamp-on Ultrasonic Flow Meter. Ultrasonic clamp-on meters have been a leading meter in building design and construction HVAC facility and property management water and wastewater treatment and water distribution industries for decades. Siemens claims a proprietary means of compensating for various piping anomalies.

This flow meter can be used for the measurement of underground water potable water waste. We are able to hear the sound because the vibration frequency is in the audible range about 20 hertz to 20000 hertz. How much straight pipe do you need.

The new flowmeter system see Figure 1 consists of an electronics console clamp-on ultrasonic transducers con- necting cables and a clamping fixture to hold the transducers solidly in place on the pipe. Ad Die Wegbereiter für kluges Online-Shopping - jeder Kauf eine gute Entscheidung. Flow Measurement SITRANS FS ultrasonic Clamp-on ultrasonic flowmeters SITRANS FSS200 ultrasonic flow sensor 3 Function continued SITRANS meter family description SITRANS FS230 clamp-on flowmeters The FS230 system is a basic function permanent or dedicated Clamp-on meter that is available with a full range of safety ap-provals and IOs.

A couplant is applied to the transducer faces to couple them acousti- cally to the outside pipe wall. Typically flowmeter manufacturers specify a minimum of 10 to 15 diameters of straight pipe. Ad High Quality Ultrasonic Flowmeter with Competitive Price.

Straight Length Requirements for Ultrasonic Flow Meters Install upstream of any flow obstacles Provide as much space between obstructions and the flow meter Can go as close as 5x but it results in an additional 1 inaccuracy in the reading Example. The Insider Blog 3 min read. LRF-2000S is one of the best-selling flow meters.

15 rows Required Straight Run to install flowmeters Technology On Flow Measurement F-0009 Required Straight Run to install flowmeters To obtain specified accuracy straight run both for upstream and downstream is needed. Better than 05 Repeatability. Flow meters which clamp on to the outside of the pipe offer many advantages over traditional in-line flow meters.

This means that for a 4 diameter pipe you would need 10 x 4 40 of straight pipe or for a 2 pipe you would need 10 x 2 20 of straight pipe. Compared with the commonly used TDC calculation method used by most of our domestic manufacturers TGA measurement technology is an. The application of Snells law of refraction is the first consideration.

Set-up requires a certain length of straight pipe to get the signal return and avoid high turbulence areas. However for more severe flow distortions you may require more. The meter interior is designed as a modular structure allowing for a high reliability and low maintenance cost.

Easy installation no moving parts no pressure loss no compatibility issues etc. KOBOLD DUK requires 10x upstream and downstream straight run requirement. Why choose a clamp-on ultrasonic flow meter.

Not all applications have the appropriate straight run available. The flow profile affects the transducer energy path through the medium so the accuracy of the measurement is influenced by upstream turbulence control valve intrusions piping configuration elbows and Tees straight run upstreamdownstream and Reynolds number. Ultrasonic flow meters operating at frequencies of vibration are outside of the audible range at 25 kilohertz or above.

These higher frequencies allow more accurate measurement as well as not generating sounds in the audible. The recommended straight run by type is shown below. A straight run of 10 up and 5 down is commonly suggested.

Discover five frequently asked questions and answers to learn more about these popular meters. Flow in the same direction takes less time to travel to the second transducer than flow in the opposite direction. You need 100 liquid no bubbles or gas pockets.

With this capability we were able to guarantee flow meter accuracy comparable to or better than mag meters. Figure 2 - Snells law of diffraction The design of clamp-on flow measurement systems allows variable configurations in signal propagation. Izzy Rivera Flexim Americas Corporation.

Also there were some flow measurement points with very short straight runs. It enjoys high popularity because of its economical price and reliable function. A Brief History Significant Milestones 1955 Doppler ultrasonic techniques were first implemented to detect valve heart motions 1963 Tokyo Keiki first introduced Doppler Ultrasonic meters to commercial markets 1970s saw the.

Clamp-on ultrasonic meters are capable of using multiple beams which mitigate the effects of short pipe runs. The principal challenge in clamp-on ultrasonic measurement is to align the transducers to maximize signal transmission between them. As it comes into no contact with the flow media it is fast and easy to install.

Three different transducer sizes are available to fit pipe sizes ranging from ½ 15 mm to 240 6000 mm. Clamp-on ultrasonic sensors on the other hand are installed on the outer wall of the pipe and thus also enable temporary measurements or a retrofitting. You need a good clean surface to clamp to both inside and out so any painted coated or galvanized pipes can be difficult to get good readings.
