Model P single flow tube rotameter for low flow rate measurement

  • rib-guided or fluted metering tubes facilitate stable and accurate readings
  • magnifier lens in front shield to enhance reading resolution
  • interchangeability of flowtubes and floats
  • ease of installation and exchange of flow tubes
  • “non-rotating” adapter feature – glass flow tubes are prevented from turning during the tightening phase of the assembly procedure
  • OPTIGRAD™ scales minimize parallax and eye fatigue
  • chemical compatibility
  • simple means of panel mounting

MODEL P SINGLE FLOW TUBE METERS

Designed for low flowrates, the model P flowmeter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical variable area meter. It is particularly suitable for metering carrier gases in chromatography, indicating and controlling gases in manufacturing processes, liquid and gas measurement in laboratories, pilot plants, flow and level indicating, etc. 150 mm Meter with CV™ Valve. Shipped completely assembled, flow meters include standard mounting fittings in a choice of materials, side plates, thick protective magnifying front shield and back plate, optional built-in control valve, and flow tubes selected from the Flow Capacities tables.

Flow tubes for these variable area flow meters (rotameters) are available with two types of scales, suitable for different types of applications
