5 How Accurate Are Ultrasonic Clamp-on Meters.

. The repeated regular execution of this process is a central element of its definition. The external clamp ultrasonic flowmeter has a measuring probe outside the pipe wall. Elbows valves and other devices that disturb laminar flow can drastically reduce accuracy.

For reference our Dynasonics TFX-5000 ultrasonic clamp-on flow meter measures flow ranges from 00733000 gallons per minute with up to 05 accuracy. Flow Velocities - 001ms60ms depending on pipe diameter and transducer Accuracy - 13 of reading -0005ms depending on application. To optimize every operation Siemens offers a comprehensive selection of clamp-on flow sensors transmitters and complete flow systems.

Ultrasonic clamp-on meter accuracy will vary depending on the brand and model. The installation of the clamp-on ultrasonic flowmeter probe is simple and probes of different sizes can detect pipes of different pipe diameters. FLEXIM meters have turned out to be better than the meters we were used to.

The XMT868i is a clamp-on flow meter certified for installation in hazardous environments such as. SUNCENT-X8 Clamp-on Type Ultrasonic Flowmeter Product Model. Well-made clamp-on meters can provide very high accuracy.

A clamp-on ultrasonic flow meter consists of at least two ultrasonic sensors mounted externally to a pipe. Want to know more about ultrasonic clamp-on meters or have a. How the flow rate is determined varies depending on the nature of the application.

Ultrasonic clamp-on meter accuracy will vary depending on the brand and model. A magnetic flow meter magmeter would be expected to give an accuracy of anywhere between 015 and 2 depending on the manufacturer and the application requirements. This accuracy advantage is due to the signal degradation caused by the pipe wall pipe scaling and installation inconsistencies of clamp-on style meters.

Fluid flow is bi-directional. Monitoring your processes with accurate clamp-on ultrasonic flow measurement leads to higher transparency improved productivity and a better bottom line. Transit-time is the preferred mode.

Typically inline meters are preferred for use in custody transfer applications. It is tightly connected to the pipe wall through a coupling agent. No need to cut pipes and no pressure loss.

For reference our Dynasonics TFX-5000 ultrasonic clamp-on flow meter measures flow ranges from 00733000 gallons per minute with up to 05 accuracy. 25mm 5000mm1 200 Outputs. Minimum Pressure - 3 bar abs.

Conventional flow meters for energy and heat are usually approved for - 2 so it is very good. It combines flow measurement capability with a cost-effective transmitter package that can be installed right at the process measurement point. Clamp-on meters typically do not attain the accuracy of in-line meters particularly those used for custody transfer or fiscal measurement in the oil and gas industry.

The TransPort PT878GC is a clamp-on flow meter designed for short-term flow surveys in natural gas pipelines compressed air inert gas or any other compressed gas application. For highest accuracy you need at least 10 diameters of straight pipe upstream and 5 diameters downstream. This indicates the lowest velocity at which the meter is able to maintain its accuracy statement.

High quality DN20 Accuracy 2 Clamp On Micro Flow Sensor from China Chinas leading Clamp On Ultrasonic Flow Meter product with strict quality control Clamp On Ultrasonic Flow Meter factories producing high quality Clamp On Ultrasonic Flow Meter products. Many HVAC professionals choose clamp-on meters as a long-term solution because they offer better accuracies than some traditional meters do even when measuring liquids with. They also share some common limitations.

Under the condition of ensuring accuracy the clamp-on ultrasonic flowmeter can measure pipes with a minimum of DN15 and a maximum of DN3000. CLAMP-ON FLOW METERS FOR PROCESS MONITORING wwwsonoteceu Process Monitoring with Non-contact Liquid Flow Meters Chapter 1 Process monitoring is the systematic recording or measurement of an opera-tion or process by means of technical aids 1. For example if a meter has a maximum velocity of 20 fts and performs accurately over a turndown of 10-to-1 then you can divide 20 by 10 to find that the minimum velocity at which the meter will uphold its accuracy statement is 2 fts.

The accuracy is usually 1 and 05 after correction. Your direct line to Siemens. With our TDS-100F we have confirmed - 1 in a test bench in Sweden.

We searched for a clamp on meter to measure 400F high temperature hot water. DigitalFlow Family of Clamp-On Liquid Flow Meters - The Panametrics DigitalFlow XMT868i is an ultrasonic flow transmitter for liquids. The portable steam flow meter allows you to carry out measurements in multiple pipe locations throughout your site.

This is mainly because of signal degradation caused by the pipe wall and liner pipe centricity and human factors with installation. The meters measure flow down to 03ftsec which is 10 times lower than the Mag meters we use. The results were so accurate that we now use one in every application.

Operating Temperature - 100c180c. Covering a wide range of flow rates Dynasonics Ultrasonic clamp-on meters for example offer impressive measurement with accuracy up to 05. Clamp-on ultrasonic flow meters can handle all types of corrosive liquids as well as gases and are insensitive to changes in temperature viscosity density and pressure.

Katronic ultrasonic flowmeters have an accuracy of 1-3 of measurement. Adopt low voltage multi-pulse technology to improve accuracy useful life and reliability. More than that is better.

But the accuracy of clamp-on meters depends entirely on the assembly. The sensors measure flow by transmitting and receiving ultrasonic signals directly through the pipe wall and the medium. The accuracy of the clamp-on ultrasonic flowmeter fully meets the measurement requirements.

420mA max load 750 Pulse output. The accuracy of clamp-on flow meters may therefore be influenced by changes in fluid flow dynamics caused by bends and junctions in piping and also by variations in pipe diameter arising from both corrosion and debris build-up. Several type transducers for selection measuring pipe size is from DN15mm to DN6000mm.

Inline meters have a longer history of use and tend to be more accurate. Additionally clamp-on meters are particularly susceptible to external vibrations as they are attached to the outside of piping.
