In-Line vs. Insertion Type Paddle Wheel Flow Meters
There are two main types of paddle wheel flow meters: in-line type and insertion type.
In-line paddle wheel flow meters are designed to be installed directly in the process pipe or channel, with the flow of the fluid passing through the meter. In-line paddle wheel flow meters are generally more accurate than insertion type flow meters, as they are able to measure the flow rate of the fluid more directly. In addition, in-line paddle wheel flow meters are generally easier to install and maintain, as they do not require any special sensors or probes to be inserted into the pipe or channel.
Insertion paddle wheel flow meters, on the other hand, are designed to be inserted into an existing pipe or channel. These flow meters typically use sensors or probes that are inserted into the pipe or channel through a small opening, and are used to measure the flow rate of the fluid as it passes by. Insertion paddle wheel flow meters are generally less accurate than in-line flow meters, as they are measuring the flow rate of the fluid indirectly. However, they are often preferred in situations where it is not practical or possible to install an in-line flow meter, such as in existing piping systems or in tight or hard-to-reach locations.
In-line paddle wheel flow meters are also relatively simple to both install and maintain. These flow meters can be easily integrated into new or existing piping systems, and do not require any special sensors or probes to be inserted into the pipe or channel. In addition, in-line paddle wheel flow meters are generally resistant to fouling and clogging, which can be an issue in applications where debris or contaminants are present in the fluid.
Overall, the choice between an in-line paddle wheel flow meter and an insertion type flow meter will depend on the specific needs of your application. In-line flow meters are generally more accurate and easier to install and maintain, but may not be suitable for all applications. Insertion flow meters, on the other hand, may be less accurate but are often preferred in situations where an in-line flow meter is not practical.
