Convergence in price differences among metal tube flowmeters

Thread Content

Metal tube flowmeters come in a wide range of prices, mainly due to differences in product types. 1. Pointer type. That is, the type with on-site instructions; this is the most basic function and it comes at the lowest price. 2. Liquid crystal type. The readings obtained from the instrument measurements are displayed on an LCD screen, making them more intuitive; it also features a 4-20mA output function. The price of this type is much higher than that of the basic model. 3. Installation type. To meet on-site requirements, metal rotameters are often customized according to the customer’s needs for vertical installation, horizontal installation, flange connection, thread connection, as well as side-inside-out types, among others. 4. Materials for production. Due to the properties of the medium being measured, flow meters use different materials in their construction. For ordinary media, no corrosion resistance is required; stainless steel 304 is sufficient. However, for corrosive media, it is necessary to use materials such as stainless steel 316, 316L, or stainless steel 304 lined with PTFE to provide corrosion protection, and such materials naturally come at a much higher cost.
