RKC INSTRUMENT LE100 General Description

LE100

General Description

Specifically designed for the measurement of liquid chemical levels.
The specific gravity compensation function eliminates the need to set liquid level with actual liquid and is easily accomplished during chemical
change.
The LE100 measures liquid levels by supplying inactive gas at fixed pressure to the sensor tube installed in the storage tank. Back-pressure is
determined by measuring the changing liquid level. The sensor tube pressure varies proportionately to changes in liquid level.
Features
Level settings 6 or 8 points
Measuring range 0 to 1000 mm
Selectable display units (mm, %, l, cc, Pa, KPa)
High repeatability 0.3% full scale
Specific gravity compensation
One - touch empty adjustment
One - touch span adjustment
Volume compensation
Digital communication (Optional)
Monitoring output (Optional)
Empty adjustment function
Empty adjustment function can adjust the displayed low limit measured
value to the purge pressure at the end of the sensor tube exposed to
atmosphere.
Specific gravity compensation
The high limit value is automatically computed and the liquid level is
displayed linearly by setting the specific gravity of the liquid and the low
limit measured value. If the specific gravity is known, the high limit
measured value can be set without presence of actual liquid.

Specific gravity compensation
with actual liquid
The specific gravity and high/low limit measured values are computed
automatically and the liquid level (mm) is displayed linearly by inputting
two optional points of actual liquid levels.

Span adjustment function
The percentage value display within a 0 to 100% range is achieved by
setting the optional high and low limit adjustment points.
