The Model S single tube flow meters are similar to P meters in design, employing the same interchangeable flow tubes, valves, and accessories. Likewise they may be panel or bench mounted. The primary advantage of the S meter is convenience in applications, where frequent changing of tubes in meter cases is desired. An example is when several flow tubes are used in conjunction with a single meter case, or when because of the nature of the fluid, periodic cleaning necessitates dis-assembly. The Flow tubes for these meters are available with two types of scales, suitable for different types of applications.
