S meter

Product catalog summary

Overview: The document provides detailed information about the Model S single-tube flow meters, highlighting their design, features, and specifications. These meters are designed for applications requiring frequent tube changes and are suitable for both panel and bench mounting.

Design Features:

The TUBELOKTM design allows for easy installation and replacement of tubes.
Rib-guided or fluted metering tubes ensure stable and accurate readings.
A magnifier lens enhances reading resolution, while OPTIGRADTM scales reduce parallax and eye fatigue.
Flow meters are equipped with interchangeable flow tubes and floats.

Built-in Valves:

Available with built-in needle valves (CVTM) or high precision metering valves (MFVTM) with non-rising stems.
Valves are recommended at inlets for gases and can be positioned at inlets or outlets for liquids.
For vacuum services, valves must be mounted at outlets.

Materials of Construction:

Flow tubes are made of heavy-walled borosilicate glass.
Floats are available in glass, sapphire, 316 stainless steel, Carboloy®, and tantalum.
Mounting fittings can be aluminum, brass, or stainless steel.
Front shields are made of Lexan® with a magnifier lens, and back plates are white acrylic.
O-rings and packing options include Buna-N®, Viton®, PTFE/Kalrez®, and EPR.

Specifications:

Standard accuracy is ±2% FS for most scales, with calibrated accuracy of ±1% FS optional.
Repeatability is ±0.25%.
Useful flow range is 10:1 minimum with one float, and better than 20:1 with two floats.
Maximum operating pressure is 200 psig/13.8 bars, and maximum operating temperature is 250°F/121°C.

Ordering Information:

Model S meters can be customized based on channel number, size, material, valve position, seals, fittings, and manifold options.
An example configuration is provided: S16S1-VA0, indicating a single channel, 65mm, stainless steel, high precision valve at inlet, Viton seals, 1/8" FNPT fittings, and no manifold.

SINGLE TUBE FLOW METERS S STYLE Model S single-tube flow meters pictured on this page are similar to P meters in design, employing the same interchangeable flow tubes, valves, and accessories. Likewise they may be panel or bench mounted. Model S Flow Meter Shown. With Optional Tripod Base and CVTM Valve The important 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 disassembly. ✹ FOR SENSOR OPTICAL H SWITC E 30 SEE PAG Aalborg’s® exclusive TUBELOKTM design facilitates simple installation and replacement of tubes in mounting cases. As a result of the “non-rotating” adapter feature, glass flow tubes are prevented from turning during the tightening phase of the assembly procedure. design features ✓ TUBELOKTM design simplifies installation and replacement of tubes. ✓ Rib-guided or fluted metering tubes facilitate stable, accurate readings. ✓ Magnifier lens in front shield to enhance reading resolution. ✓ OPTIGRADTM scales minimize parallax and eye fatigue. ✓ Simple means of panel mounting.

BUILT-IN VALVES Meters are available with built-in needle valves (CVTM), high precision metering valves (MFVTM) 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. Generally, for gas metering it is recommended that valves are positioned at inlets (bottom) for liquids valves may be positioned either at inlets or outlets (top). For vacuum services, valves must be mounted at outlets. If unspecified at the time of ordering, meters...
