1200 Turbine Flow Meter |
|
The Model 1200 Turbine Flow Meter is designed and constructed
for reliable flow measurement in rigorous chemical processing
and industrial class environments.
This design includes a rugged stainless steel meter housing
with a durable, abrasive-resistant CD4MCU-416 stainless steel
rotor along with a stainless steel rotor shaft by two stainless
steel ball bearings. The Model 1200 features an integral electronic
RF pickup to improve the meter's operating efficiency at the
low end of the flow range. |

Principle |
|
The Model B1200 Turbine Meter design
includes a pair of hydrodynamically shaped deflector cones
to supplement the flow straightner sections in stabilizing
the fluid flow pattern (turbulent to laminar) through the
meter. This laminar flow pattern causes the rotor to operate
more consistently, at speeds proportional to the fluid velocity
passing through the rotor's turbine blades.
The rotating turbine blades modulate a high frequency carrier
wave in the externally-mounted RF pickup,creating a 5-volt
DC square wave (output signal). |
