volume. The total number of pulses collected over a period of time represents the total
volume metered.
•
The sinusoidal signal from each pickoff has a low amplitude and is not normally relied
upon for transmission distances over 6 meters (20 feet). The signal must, therefore, be
amplified. This is achieved with a preamplifier contained within the LME that is
mounted on the turbine meter.
•
These pulse signals are typically transmitted to control room instrumentation, such as
flow computers, and may also be required to transmit to prover computers which
calculate, display, transmit, control or record the flow sensed by the rotor. The results
may be displayed as pulse-counts or standard engineering units, such as gallons, liters,
barrels, etc.
•
All Daniel Series 1200 Liquid Turbine Meters have, as standard, the LME which is fitted
with two pickoffs and a dual channel preamplifier.
•
The pickoff mountings are oriented so that the outputs from the pickups are 90º
electrically out of phase.
•
Each turbine meter is precisely flow calibrated before shipment.
