I have a question regarding the float models for metal tube rotameters
Thread Content
Float shape: Water DIV CIV, Air TIV DIV DIVT. What do these mean respectively? Also, how do I choose the spinal canal number? Are there specialized selection software tools available to calculate the required diameter of the flow meter and its pipe size? I hope the experts here can help me explain it. PS: I’m just a newbie at the design studio, so there’s a lot I don’t know!
Reply to 1# cao2011: DIV CIV are the models of rotors or floats commonly used for liquid measurement, while TIV, DIV, and DIVT are the models of rotors or floats used for gas measurement. The DIV designation is used for both types because these types of floats or rotors allow the measurement range to be increased by 50% under the same cone shape.
The float numbers and models vary from manufacturer to manufacturer
Yes, it refers to the float code and model, which vary from manufacturer to manufacturer. For our Chuanyi manufacturer, the float codes are CF and DF
During the design process, there is no need to select the cone tube size or the float type; it is sufficient to calculate the instrument diameter and specify the flow range. The manufacturer will then choose the appropriate cone tube size based on the flow rate. Additionally: the float numbers vary among different manufacturers, and some of them use orifice plate types.

Why not ask the technicians in your workplace and those in the surrounding area? They are the ones closest to you as mentors, and they may be familiar with the specifications and models of flow meters of the brand you mentioned. Additionally, the selection of a rotameter is carried out using the manufacturer’s specialized calculation software, taking into account the process conditions and medium parameters provided by the designer; the selection includes the meter’s cone tube and the appropriate float, as well as the specifications for process connections. You only ask about the meanings of a few abbreviations; who knows? Unless a technician who knows how to manufacture such flowmeters happens to see it.
