Ultrasonic flow meter is famous for its unique way of clamp on installing. This feature provides non intrusive flow measurement for closed pipe.  We have involved with ultrasonic flow meters for decades of years and accumulated strong power in developing/manufacturing. Based on this, we are able to provide complete customizing OEM service from hardware to software.  This service can improve your brand credit and protect your maketing to avoid competition.

Clamp on ultrasonic flow meter is also called as clamp on flow meter or clamp on water flow meter.It can measure liquid volume flow from outside of closed pipe. Clamp on flow meter is developed on the basis of ultrasonic non-invasive technology.Ultrasonic technology mainly have two: transit-time and doppler. Transit-time flow is used to measure clean liquid, or liquid with average bubbles or particles. Doppler is mainly for dirty liquid flow measurement.

Clamp on installing way doesn't need to cut pipe,so it doesn't need to stop flow, and won't influence normal manufacturing job. The flow meter doesn't contact water directly, and does't pollute fluid. Clamp on feature makes it easy and convenient to install and operate,and it 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,users are no need to replacement parts, because no mechanical wearing.

Low Cost Ultrasonic Flow Meter

 

Low Cost Din-rail Mounted Ultrasonic Flow Meter (9-36Vdc Power)

The 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 flow meter can be used for heat flow meter/BTU meter. It has compact body and low price,but its function is still powerful. Small size body can bring light weight to reduce express shipping cost for international plane shipping.

Clamp on water flow meter

 

Main Fixed Type Ultrasonic Flowmeter (100-250Vac/ 9-36Vdc power)

Wall mounted flow meter has a rugged IP65 water-proof enclosure.It supports power of AC90-250v/DC8-36v. Over 7 generations developing has proved its strength. Standard Modbus makes it network easily.

A built-in SD card data logger is optional,supporting Max 8G. The latest data software is optional. 

 

Handheld ultrasonic flow meter

Handheld Ultrasonic Flowmeter (Rechargeable Battery)

Handheld ultrasonic flow meter has very low price and well sold in the world. With compact design, it can be held by one hand only. Its built-in battery can work over 10 hours after fully recharging.

The flow meter has a built-in data logger. By our latest management software, data can be stored to computer for further processing.

 

Not Just Clamp On Flow Available

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.

More Details to Know

Clamp on ultrasonic flow meters mainly have three parts: flow converter,flow transducer(flow sensor) and special connection cable.Flow converter is the main unit and in charge of processing.The function of converter is similar to brain of human being. Flow transducer is sensing parts to detect flow signal. Flow signal is sent to converter by cable. Then, converter processes related signal and get corresponding data.Digital signal process(DSP) is introduced to ensure the meter performance. If you want to buy clamp on ultrasonic flow meter,it is better to buy the 3 parts together.
Clamp on flowmeters mainly have two big 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 flowmeters are used for flow check and comparison.
In the past, when mentioned flowmeter, first concept was inline type like water meter. Even by now, many technicians still keep such memory. But as the quick development, more and more users prefer to select clamp on flowmeter as their priority choice.Several years ago, the price of clamp on meter was very expensive and only VIP users can afford it. Thanks to technology improvement, several companies have devoted to reduce its price. As one of main player in the industry, we have been working hard for over 20 years.Luckily,we have sharply made its price lower. This can make more users have opportunity to experience such advanced flow devices.
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.
In order to make flowmeter work properly, you at least require to order one electronic flow converter and one set of flow sensors.
