Wallace &
Tiernan Metal Tube Bypass Rotameter
Metal Tube
Bypass Meters allow rotameters to be used for larger pipes and flows
instead of a differential pressure meter. The flow rate through the bypass
meter is proportional to the flow in the main pipe.
By-pass Varea-Meters
are shipped with the orifice in place, ready to install. No mercury or
bellows-type manometer required. Checking or snubbing devices can be
omitted as over-ranging is harmless. For indication, a 1/2-inch Glass Tube
Varea-Meter is available with 5 or 10-inch scales, threaded or flanged
horizontal connections, and in a variety of materials.
This
straight-through meter is available in a 1/2-inch tube size with 316
stainless wetted parts. Flanges can be carbon steel, 316 stainless. Flange
limits are 720 psi and 600 F. Can be supplied with a magnetic indicator,
with optional 4-20 mA flow-rate transmitter, and optional flow switch.
When the metal tube meters float is at rest, float extensions do not
project beyond the flanges. Installation is simplified. No spool pieces
required.
