Selection of feed flow meter for reaction kettle

It’s easy to install; just place it a little above the mouth of the kettle

The rotameter must be installed vertically, with the inlet facing downward; the inlet section should have a straight pipe section with a length of 7 times the diameter of the rotor

I know that. It is precisely because of such requirements that I asked where the rotor on the feed pipe of the reactor is usually installed

The reaction vessel is designed as a rotor – aren’t you strict regarding measurement requirements? Nowadays, mass flow meters are generally used; they hardly ever fail and provide accurate measurements. In such important locations, installing a good flow meter is beneficial for measurement, for process analysis, and it results in a low failure rate. In our company, when we see that a design institute has designed something as a rotor, we usually ask them to make changes; in most cases vortex flow meters are used for measurement, mass is utilized in certain situations, and electromagnetic devices are employed in other cases. At the pump inlet, balance mechanisms are generally used where there is significant vibration. Rotors have many installation requirements, a high failure rate, and are difficult to handle; it’s better to avoid using them if possible.

Generally, there’s no need to consider this oneself; the PID for the installation location is specified, and installation instructions are available in the installation diagrams, which are usually provided by the design institute

Generally, rotameters are installed on-site. Even if you use a rotameter with remote transmission capabilities, why not consider other types such as orifice plate differential pressure, vortex flow meters, mass flow meters, or electromagnetic flow meters, which all offer higher accuracy than rotameters? Only a remote-flow meter system can be operated from the control room.

Check the properties of the medium, pressure, toxicity, and so on. Determine what measuring tools to use again. For example, a water meter is sufficient for water. Generally, chemical reactions are metered using metering tanks.

It is advisable to avoid using rotors for feeding into reaction vessels; although there are rotors with feedback mechanisms, their precision is not high, making them unsuitable for applications that require accurate measurement in reaction processes

It can be installed vertically in a location where it is easy to observe
