Clamp On Flow Meter Brief

Clamp on ultrasonic flow meter is famous for its unique non-invasive installing,which provides non intrusive flow measurement for closed pipe.Clamp on flow meters are also called as clamp on water flow meter,strap on flow meter,non contact flow meter,etc.It can measure liquid volume flow from external surface of closed pipe.The flow meters are mainly developed on two kinds of ultrasonic principles: transit-time and doppler. Transit-time flow meter is used to measure clean liquid, or liquid with average bubbles or particles,and typical application is water,fuel,alcohol,etc. Clamp on Doppler flow meter is mainly for dirty fluid measurement.

Strap On Flow Meter Features

Strap on flow meter provides non contact flow measurement that means the flow meter doesn't need to cut pipe and no need to stop flow. This is unique and unlike other type flow meters. Many customers don't hope to influence normal production schedule while installing or future management. The non contact flow meter doesn't contact fluid directly, and avoid a secondary medium pollution. Strap on feature also makes it easy and convenient to install and operate,and also reduces the installing cost and material cost. Because no pipe cutting,there is no risk of leakage,and almost no maintenance cost in future. Without moving parts,strap on flow meter has no pressure loss and users are no need to replacement parts,meanwhile,the good performance can be ensured for long-term.

Main AC/DC Fixed Type

Wall mounted ultrasonic flow meter has a rugged IP65 water-proof enclosure.It supports power of AC90-250v/DC8-36v. Over 10th generations are developed to prove its strength. Standard Modbus makes it network easily. A built-in SD data logger optional for Max 8G. Latest data management software available.

 

Low Cost Ultrasonic Flow Meter

The DIN-Rail flow meter is designed for large quantity application with low budget.Of course, small project can select it as its price is very low. But its function is still powerful and supports various flow sensors,too.The low cost flow meter can be used for heat flow meter/BTU meter. Though low price,,but still powerful.

Portable Ultrasonic Flow Meter

Portable flow meter for mobile flow check and survey.Handheld unit can be held by one hand only.Built-in battery can work 12 hours after recharging.Data can be easily stored to built-in data logger for further processing.Built-in printer optional.

Non Contact Flow Meter Kit:

Non Contact flow meters mainly have three parts: converter,clamp transducer(flow sensor) and special cable.Converter is electronic processor,clamp on transducer sensor detects liquid signal. Liquid signal is sent to converter by cable.Digital signal process(DSP) is introduced to the system. A complete of non contact flow meter at least requires the 3 parts.

In order to make ultrasonic flow meter work properly, you at least require to order one electronic converter and one set of flow sensors.

Low Cost Ultrasonic Flow Meter

When mentioned clamp on ultrasonic flow meter,many people have the first memory:it is too expensive,but in fact, it was old memory.Thanks to our experienced R&D team, we have successfully made its price very low. In the past,clamp on flow meter was always very expensive and only well-budgeted projects can afford it. Now because of low cost and good performance,more and more users prefer to select our clamp on flow meter as their priority choice. Clamp on ultrasonic flow meter is almost the only solution for the application where pipe cutting is not allowed at present. With high cost-effective solution, our ultrasonic flow meters have been well sold  in the worldwide.

CLAMP ON FLOW SWITCHES

Relay switch outputs can make clamp on flow meters work as clamp on flow switch. The relay switch is weak current and need an intermediate relay to control strong current equipment,e.g. pump.

Not Decide Yet,Check Now:

Ultrasonic flow meters have two big main types:fixed type and portable type. Fixed type, as its meaning, is fixed installing.It is used to monitor one pipe for long term.It includes several different flow converter,e.g.wall mounted,desktop,flow transmitter,low cost din-rail mounted,etc. Portable flow meters mainly have handheld type and standard version. Handheld type has a compact size and light-weight.It can be held by one hand. Standard version has a longer battery life and bigger size body. It can be equipped with mini printer for local data output.Portable ultrasonic flow meters are used for flow check and comparison.
Generally speaking,clamp on flow meter is your top consideration as you have decided ultrasonic flow meters. Clamp on type doesn't need to cut pipe and avoid many complicated jobs.You will feel so easy and comfortable to install clamp on flowmeter. But if the pipe condition is very poor or not suitable for ultrasound, e.g. serious rusted, cement pipe,etc, clamp on type won't be able to work. At this time, insertion flow meter is a better choice. It just requires to drill a very small hole in the pipe and can be installed without flow stop. Meanwhile, its weight is very small and can save shipping cost. Insertion flowmeter almost has no requirement for pipe material. Inline flow meters are the most common type and many flow devices utilize inline structure. But inline ultrasonic flowmeter belongs to real digital flow meter. It has no moving parts and have a higher accuracy and longer life.Comparing with mechanical flow meters,it also has other unique advantages. Thus,inline ultrasonic flowmeter is still one good solution.
