The model Px multiple tube flow meter offers, the convenience and simplicity of 2, 3, 4, 5 and 6 tube meters, retaining most of the unique design features associated with single tube units (like our model P). Multiple tube meters are available with 65mm or 150mm flow tubes. The same flow tubes as in single unit flow meters. Px meters are convenient for applications where several streams of gases or liquids are to be metered in individual channels, or manifolded.
Shipped completely assembled, flow meters include standard mounting fittings in a choice of materials, side plates, thick protective front shield and back plate, optional built-in control valve, and flow tubes selected from the Flow Capacities tables.
Flow tubes for these meters are available with two types of scales, suitable for different types of applications.
Meters are available with built-in needle valves (CV), high precision metering valves (MFV) with “non-rising stems”, or with no valves. The higher cost of MFV valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flow rates.
