A plastic tube flowmeter is an ideal choice for applications involving low-cost measurement of liquids and gases. These flowmeters can be supplied with various seal and float materials and are suitable for a variety of chemical solutions. However, the choice of material can also be confusing. Listed below are some tips for selecting a suitable model. They should be suitable for the fluid and process that will be measured.
Plastic tube flowmeters come in different shapes and sizes. Some are designed for specific applications, such as industrial cleaning. Others are ideal for applications involving light industry, health care, and environmental drainage. They have two different types of connections, one for the pipe and one for the float. Plastic tube flowmeters are typically threaded or flanged. The base of the flowmeter is made from either stainless steel or plastic.
A plastic tube flowmeter may have a steel end connector or a PVC-nut. The latter type is usually designed for higher pressures. The small tubes, six mm (1/4"), are suitable for working pressures up to 500 psig, while larger 51 mm (2") tubes operate at less than 100 psi. Regardless of the material, the end connectors must be carefully selected to suit the requirements of the application.
