PRINCIPLE OF OPERATION

The Turbo Steam Meter is comprised of 4 major components: body with range orifice, by-pass with rotor, reduction gear chamber and direct
reading counter.
The total steam flow is divided in the main meter body and a proportional flow passes through the nozzle and bypass. Smooth operation of the rotor is assured by a direct coupled dampening fan operating in a pool of a chamber below the turbine.
The damping torque of the sub-merged fan and the turning torque of the measuring rotor are balanced to produce a shaft rotation speed pro-proportional to the total flow through the meter body. This shaft rotation is transmitted through a magnetic coupling to a computing gear train in the register. Steam flow totals are provided by the direct reading dial and counter in the register. A pulse generator can be located in the register to provide for flow transmission to a remote totalizer.
High accuracy is assured by the use of anti-friction bearings throughout.
Hard carbon bearings are used at the measuring rotor. Sapphires are used for the lower shaft bearing. All parts are designed to operate smoothly for long periods at high temperatures.

CONFIGURATION

FEATURES

1. Wide flow range and high accuracy.
2. Greatly extended service life (more than three times that of previously offered model).
3. Minimized pressure loss. Energy loss substantially reduced.
4. Very simple installation procedure no pipe taps required.
5. Can readily change range orifices without removing meter from pipe line.
