How Do Insertion Magnetic Flow Meters Work?
Insertion flow meters measure the flow of conductive fluid within a closed system. These meters comprise a junction box, measuring head, mounting base, insertion rod, excitation system, positioning, and sealing mechanism. First, a specified size hole is drilled into the fluid system, and secured with the help of a weld-on threaded stub or a mating flange. Next, the insertion-type flow meter is inserted to the required depth.
Equipped with sensors, including ultrasonic and thermal, they detect and analyze different fluid flow parameters, such as temperature, pressure, and velocity. Insertion flow meters collect data points when the fluid passes by the sensors. These data points are transmitted to the control unit of the meter. The control unit utilizes signal processing algorithms to analyze the data. The flow rate readings are then displayed on the meter’s screen for monitoring and analysis.
How Insertion Magnetic Flow Meters Help Improve Accuracy in Industrial Fluid Measurement
Insertion magnetic flowmeters are a cost-effective solution to improve process efficiency and reduce variations in industrial processes by accurately measuring fluid and gas flows. They are ideal for various applications, such as HVAC systems, water treatment plants, chemical processing plants, and so on. You can fit them in existing systems as part of an upgrade as it is quite easy to install and maintain. Here are some pointers.
- Insertion mag flowmeters can be retrofitted easily as they have no moving parts and hence, are low on maintenance and can function without disrupting the fluid or gas.
- They are battery-powered. The signal output can be fed by using this device along with a programmable logic controller.
- Insertion flow meters measure the flow of liquids in a wide range of pipe sizes and materials, including plastic, metal, and concrete pipes.
- They can be calibrated to account for variations in pipe size and fluid properties, which helps ensure accurate readings.
- These flowmeters have a touch keypad through which rates and total units can be keyed in by the user. This whole mechanism makes it simple, easy to use, and accurate.
- They are more accurate than most other tools because these flowmeters directly measure the mass than the volumetric flow, which is a key requirement for process control.
Calibration Process of Insertion Mag Flow Meters
Regular periodic calibration of measuring tools is necessary to ensure the accuracy and long lifespan of the device. It is necessary to follow the calibration guidelines given by the manufacturer. Also, it is important to conform to NIST standards.
Depending on the application requirement, there will be a set value or predefined standard against which the meter needs to be calibrated. Their value is compared and adjusted based on the set value. Calibration is done for the first time the meter is used, while recalibration is carried out periodically to ensure the meter provides accurate readings. There are software tools to validate the required level of accuracy post-calibration and recalibration. Here are some pointers.
- While there are various calibration methods, calibrating a master insertion flowmeter as a standard for further recalibration is the most common.
- Calibrate a flowmeter as a master or a standard one by placing it under test with the flowmeter.
- Compare both the readings based on the flow volume measured.
- Ensure to calibrate at multiple or a range of flowrates based on the operational requirement.
- Now calibrate the flowmeter under test based on the master one to ensure it conforms to the master device calibration.
- Recording and documenting this process, reference readings, and other relevant information is important.
Difference Between Inline Flow Meters and Insertion Flow Meters
Here are some differentiating factors between inline and insertion magnetic flowmeters.
- While both are installed inside the pipelines, insertion flowmeters measure the flow velocity of fluids or gases in specific pipeline areas and then the average volume can be determined. On the other hand, inline flowmeters measure the average speed of the fluid or gas flowing through the entire section of the pipe.
- Insertion meters are easier to remove and clean compared to inline meters. This is essential in applications such as wastewater, chemicals, etc.
- Insertion meters are easier to install than inline meters, and the former can be installed without cutting the pipes. They can be welded into the pipe after being inserted via a drilled hole. On the other hand, the installation process of inline flow meters is a bit complex and involves cutting the pipe to match the size and diameter.
- Insertion flow meters are suitable for pipes with large diameters, while inline flow meters need to be customized to suit large pipes, which increases the cost.
- Inline flowmeters, although expensive, offer better accuracy than insertion flow meters. If your application requires highly accurate flow measurements, inline flowmeters would be the right option. However, if the required level of accuracy is not very high, insertion magnetic flowmeters may be the right option.
Types of Insertion Flow Meters Offered by Cannon Water Technology
At Cannon Water Technology, we offer the following types of insertion flow meters:
- Fixed Depth Insertion Magmeter: This type of insertion magnetic flow meter uses the principle of magnetic induction to measure the fluid flow rate. It is designed to be installed in different sizes of pipes with a fixed insertion depth. The flow meter ensures accurate and consistent flow measurements since the sensors are always positioned at the same distance from the pipe wall.
- Depth Insertion Magmeter: Depth insertion magmeters are slightly similar to the fixed depth insertion magmeter. However, they are designed to be inserted at a variable depth into the pipe. They are typically used in applications where the measured fluid has a relatively low flow rate.
- Hot Tap Adj Depth Insertion Magmeter: A hot tap adjustable depth insertion magmeter is a type of flow meter designed to be installed in a pipe without the need to shut down the flow of the fluid being measured. The hot tap feature of this magnetic flow meter allows it to be installed without interrupting the flow of the liquid, making it a more convenient and cost-effective option for some applications.
