Clamp on Ultrasonic Flow Meter

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.

Portable Ultrasonic Flow Meter

Portable ultrasonic flow meter is designed to provide accurate liquid flow measurement in closed pipe.The portable flow meters are suitable for clean liquid or liquid with average bubble or particles. The liquid mainly includes potable water,ultra-pure water,sea water,sewage water,river water,alcohol,clean oil,etc.With clamp on flow transducers and battery power, portable flow meter is an ideal powerful tools for flow checking,comparison and survey. Light weight and rugged protection case make it convenient to carry.

Portable clamp on flow meters mainly have two kinds of flow converters:portable flow meter and handheld flow meter. Portable water flow meter has a bigger size,and has a longer battery time.Handheld flow meter has compact design and lower price. Portable flow can be also equipped with micro printer for spot data printing.

Handheld ultrasonic flow meter has a compact size and can be held by one hand. Portable type has a RS485 port or 4-20ma optional.Handheld unit has a RS232 9-pin port. Of course, this is not big difference. Handheld flow meter can be specially made with RS485 port or 4-20mA output.But if requires printer, portable flow meter is the sole choice. Otherwise, handheld flowmeter is a better choice because it has a higher cost-effective feature.

Battery Ultrasonic Flow Meter

Ultrasonic water meter is specially designed for accurate water flow measurement.It is developed on the principle of transit-time technology. Based on our patented low power consumption design,ultrasonic water flow meter can work for 4-10 years just by one piece of D size battery. As ultrasonic water meters are often installed in harsh environment,it is at least IP65 class water-proof, and higher class IP68 can be ordered as requirement.

As developed from ultrasonic inline&insertion flow meters,ultrasonic water meter also inherits related advantages from them.For example, no moving parts, no pressure loss, higher accuracy, wide flow range,low flow startup,digital display,etc. Meanwhile,ultrasonic water meter also has its main advantage-low power consumption and can be powered by built-in battery only. Thus,it is ideal to use for remote area without external power available.

As flow sensors, our ultrasonic water flow meters have two types: standard inline style and insertion hot-tap. Inline style is often seen everywhere because most of water meters and flow meters are using such design.Insertion type is developed for bigger pipe size with higher cost-effective. Inline type is easier to install. We also provide patent hot-tap installing tool for insertion flow sensors. With the tool, insertion water meters can be installed without flow stop while water pressure is below 0.8MPa. The tool can be used for repeated purpose.

At present, ultrasonic water meters are gaining more and more market share.It has a very promising prospect. It is the ideal choice to replace mechanical water meters in the world. Even though compete with electromagnetic water meters, ultrasonic water flow meters still have many advantages.

Magnetic Flow Meter

Electromagnetic flow meter provides accurate volumetric flow measurement for liquid in closed pipe. Electromagnetic flow meter is often called as: magnetic flow meter,mag flow meter,mag meter,mag-meter,electromagnetic water flow meter,etc. No matter what is called, magnetic flow meter is a kind of high accuracy flow device.Magnetic flow meter has been proved its strength in liquid flow measurement and widely used in the world.

Doppler Velocity/Level/Flow

Doppler velocity sensor utilizes doppler effect principle to measure sewer fluid velocity in open channel or partial and full pipe. With built-in sensing elements for temperature and pressure, the doppler flow meter can measure velocity, level, water temperature and flow rate.

Encased with engineering plastic enclosure, the doppler velocity sensor is completely sealed without ports and orifices. Without moving parts, there is no problem of silt blocking and grass entanglement. The probe is also solid and durable, and meanwhile it is easy to install and use. It can be installed under the water and the default depth is 10m, bigger depth (up to 100m) can be customized.

With velocity sensing point at front, doppler velocity sensor doesn’t damage flowing field, and feature high accuracy, wide range, high resolution, quick response time, etc. It can measure instant velocity and average velocity of at weak flow side or strong flow side. Linearity measurement and flow velocity calibration curve are not easy to be changed.

The doppler velocity flow sensor only has 3cm height and it can start measurement once probe submerged in water. When water level is 10cm higher than doppler sensor, it can start to work normally, thus it is especially suitable for application with low water level.

The doppler flow sensor can monitor velocity, level and temperature at the same time. If equipped with electronic converter, the doppler flow meter can easily calculate instant flow rate and flow totalizer with universal standard, e.g. full pipe, partial pipe, open channel, etc.. The flow sensors have been widely used for irrigation open channel, municipal sewer, hydrological basin and other applications.

Paddle Wheel Flow Meter

The paddle wheel flow meter is a kind of economic water flow sensor. It measure flow by using impeller.It belongs to velocity flow device and can measure water in closed pipe.It features low cost ownership.The paddle wheel flow sensors can support pulse output. Insertion installing way make its has a light weight and similar to the data industrial flow sensors.

Hall Effect Water Flow Sensor

Hall effect flow sensor provides low cost solution for water flow measurement. Hall effect water flow sensors include 3 main parts: sensor body, hall effect part and paddle wheel sensor. There are 3 kinds of material for the flow sensors. They are stainless steel, copper and plastic plastic(e.g.POM). Stainless steel is expensive, so it is not main selling item. Thus, we will mainly introduce copper and plastic.

Hall effect water flow sensors can sense water flow by built-in wheel sensor. By the operation the flow sensors can calculate how much liquid flows through it.The hall effect parts inside flow sensor is sealed from the liquid and can make the sensor under dry and safe status. When flow sensors start to count flow rate, the magnetic hall effect sensor outputs an electrical pulse with every period.

The low cost water flow sensor is mainly used for small pipe size and usually below DN50mm. It supports hall effect pulse output and can output pulse to PLC, oscilloscope, or other pulse counter device. The pulse from hall effect sensor is simple square wave,thus it is very easy to use. With the pulse output, user can log and convert it to flow rate at liters per minute. The flow rate and pulse has certain formula relationship.

We can also supply secondary flow totalizer to gather pulses from the hall effect water flow sensor. By the flow totalizer, flow rate is accumulated.

Liquid Water Flow Switch

Flow switch is used to monitor fluid flow rate in closed pipe and then provide switch ON/OFF output signal as set point. When flow rate is higher or lower than set point, water flow switch will transmit switch or alarm signal to control system. Control system will do corresponding action to control water flow accordingly for example, when flow rate is over upper limit or lower limit, flow switch will produce switch signal to open pump or close pump.

Flow switches are developed on the basis of flow meters and flow sensors. A whole of flow switch usually requires two parts: flow measuring part and switch signal module. Switch signal is sent on the value of flow rate. Thus,the real-time flow rate is a deciding factor of the accuracy of flow switch.

Flow switch looks simple to manufacture. But in fact, it is not easy. Many companies are supplying flow switches,but many of them can’t provide a reliable flow measuring unit with good accuracy. By contrast, we have dealt with flow instruments for over decades of years and have accumulated rich experience in design and making. We are your reliable partner.
