Ultrasonic Insertion Flow Meter

Ultrasonic Insertion Flow Meter-Lined/Large Pipe flow meter

The Ultrasonic Insertion Flow Meter consists of a converter and a pair of insert sensors. The plug-in sensor consists of a positioning base, a ball valve, and a sensor core. Principle: When ultrasonic waves pass through the liquid, the liquid has a slight influence on the insertion time. The change of the insertion time is proportional to the liquid flow rate.

Ultrasonic Insertion Flow Meter for Lined/Large Pipes

Insertion Flow Meter (Model:2000S) solves the problem of signal attenuation when ultrasonic Clamp-on flow meter works for a long time and the problem of fouling on the inner surface of the pipe without receiving the signal. It can be installed without stopping production. The plug-in sensor can be installed by only opening two mounting holes on the surface of the pipe. Using the hole-opening tool, the plug-in ultrasonic sensor can be installed without stopping the water. Because the sensor is in direct contact with the fluid, the measurement is stable and reliable.

Why use Ultrasonic Insertion Flow Meter?

There are 5 conditions to use Ultrasonic Insertion Flow Meter:

  • When the pipe diameter is large, the pipe diameter is generally ≥DN80mm;
  • When there is a tight inner lining;
  • When the scale in the pipe is serious;
  • When the pipe is a poor conductor of ultrasonic;
  • When the external clamped ultrasonic flowmeter probe cannot reach the required signal strength or the measurement is unstable.

In the above cases, the use of Insertion Flow Meter can be considered.

Large Pipe Flow Meters

The cost of monitoring the flow in a large diameter pipe is very high. Today, modified intrusive and clip-on flowmeter technology can be used to measure flow in large pipelines. Using plug-in flow meters, it is possible to monitor the flow in pipes up to 6000 mm in diameter.

Of course, except for ultrasonic flow meters. There are other flow meters suitable for liquid flow in large-diameter pipes.

When measuring the liquid flow of large-diameter pipes, the following factors should be considered when selecting a flow meter:

  • The pressure loss should be as small as possible;
  • Due to the low flow rate (to reduce operating costs), the inner wall of the pipeline is easy to deposit dirt and sludge;
  • The measuring range of the flowmeter used should be particularly large to adapt to the disparity of browsing in different time periods;
  • The protection level of the flowmeter should also meet the requirements of the environment.

Insertion Flow Meters

The insertion flow meter can provide a low-cost alternative to full-caliber flow equipment. Full-caliber flow equipment will take up a lot of space and require a lot of installation work. And there are special difficulties in service or calibration.

Drill a hole of appropriate size in the pipe wall. And a method of fixing the insertion gauge is adopted. This can be a saddle clamp, a welded threaded short tube, or a mating flange.

Then insert the plug-in gauge into the pipe to the depth recommended by the manufacturer. If on-site calibration is possible, the depth can be adjusted to improve accuracy.

Once the meter is fixed, it will only measure the speed at this time. And the volume flow cannot be calculated before considering the pipe diameter and the nature of the medium. Usually in the electronic flow computer/display unit.

How does the Insertion flow meter work?

Insertion flow meter has a variety of working principles to choose from, including impeller, turbine, Karman vortex, electromagnetic, thermal mass, and pitot tube. They all provide what is considered the most important feature of the Insertion flow meter. That is, they can be inserted into existing pipelines. And has all the benefits needed (see the advantages below).

Our series of flow measuring instruments for large pipelines is shown below.

The electromagnetic flowmeter is made according to Faraday’s law of electromagnetic induction. It is widely used in the flow measurement of various conductive liquids in industrial processes.

The main features of electromagnetic flowmeters are as follows:

  • There are no moving parts in the pipeline, no flow blocking parts, and almost no additional pressure loss during the measurement.
  • The measurement results have nothing to do with physical parameters such as flow velocity distribution, fluid pressure, temperature, density, and viscosity.
  • The measurement accuracy is high and the measurement range is large (up to 200:1).
  • The requirements for straight pipe sections are relatively low and easy to meet.
  • There are products with large caliber and meeting protection requirements.
  • The price of large-caliber products is higher, and the larger the caliber, the faster the price increase.

The price is lower. But it is only suitable for measuring clean liquid fluids. Otherwise, it is very easy to cause the turbo to get stuck. It is not realistic to install a filter with a mesh number that meets the requirements on a large-diameter pipeline.

Insertion Vortex Flow Meter is used on large-size pipes. Reduce piping installation to save costs. The insertion vortex flowmeter is mainly used for large-caliber gas, liquid, and vapor medium fluids. When measuring volume flow, it is hardly affected by fluid density, pressure, temperature, and viscosity. With a plug-in structure, there is no need to cut pipes and drill welded flanges. Just plug it in, easy to install. Greatly save labor costs and product costs.

The dirt resistance is better than the Insertion turbine flowmeter. The measurement accuracy is not bad either. But the lower limit of the measurable flow rate cannot be too low. When measuring the water flow, the lower limit of the flow velocity can only reach 0.3m/s. Otherwise, it will not be competent.

The differential pressure-average velocity tube is a metal central control rod that traverses the diameter of the pipeline. There are multiple measuring holes on the front face. Used to measure total pressure. There are one or more pressure measuring holes on the backflow surface. Used to measure static pressure.

Due to its simple structure, low price, and convenient maintenance, the differential pressure type uniform velocity tube flowmeter. It is more used in large-caliber water flow measurement.

The disadvantage is that the sediment in the water can easily block the sampling hole and cause malfunctions. It needs to be removed regularly depending on the size of the sediment content in the fluid. When the relative flow is small, the error will increase. Therefore, it is only suitable for general detection and control.

Insertion target flowmeter is based on the traditional target flowmeter. With the development of new sensors and microelectronics technology, a new type of capacitive force induction flow insertion target flowmeter is developed. It has both orifice plates and vortex Street and other flowmeters have no moving parts. At the same time, they have high sensitivity and accuracy comparable to positive displacement flowmeters. Wide measuring range.


Insertion target flowmeter has good adaptability in the working conditions of small flow, high viscosity, easy to condense and easy to block, high and low temperature, strong corrosion, strong vibration and other flow measurement difficulties.
Mainly used for flow measurement in various fields such as metallurgy, petroleum, chemical industry, energy, food, and environmental protection.

Insertion thermal gas mass flowmeter has the advantages of small size, high degree of digitization, convenient installation and accurate measurement.

The sensor part is composed of two reference platinum resistance temperature sensors. A bridge loop is used. One sensor measures the flow temperature. The other sensor maintains a constant temperature difference higher than the fluid temperature. Flow measurement can be performed under high temperature and high pressure conditions.
