INTRODUCTION
General
The Model IT150N Industrial Remote Totalizer is a battery powered device that provides flow totalization
in any engineering unit. Total is displayed via an 8 digit liquid crystal display. Reset of the totalizer is
accomplished externally by a magnetic field. This particular feature retains the unit’s integrity permitting
complete operational control in hazardous environments.
Negatives previously associated with LCD’s – poor cold temperature performances, condensation which
is a byproduct of heaters and display ghosting have all been eradicated by incorporating a low
temperature coefficient LCD (-35
temperature specs of –40 to 125
In addition, the IT150N provides 1 digital interface output. The scaled pulse output is an open drain
configuration in which the pulse amplitude assumes the level of the host device. One pulse is generated
for each increment of the totalizer.
Theory of Operation
The IT150N amplifies and shapes the incoming pulses generated by the turbines response to flow. The
amplified pulse train is then scaled and divided to produce a totalized display in the desired engineering
unit.
Calibration
Field calibration is accomplished by incorporating a calibration factor based on the turbine K-Factor. A
divider switch provides divisional increments of 10X from 1 to 10,000. The calibration factor is entered
via 4 BCD switches, a divider switch, and a 0-1 dip switch. The calibration factor range is 0.00000001 –
1.9999.
