The
LVN-2000 uses a vacuum source such as an injector or a Water
Champ® chemical induction mixer to draw the chemical from
the supply tank to the point of application. Utilizing the
extremely reliable and field proven Wallace & Tiernan
V-Notch control valve, reliable feedrates can be maintained
with either manual or automatic control schemes using the
SCU or PCU controllers. A direct reading flowmeter provides
accurate indication of feedrate in GPH or LPH. An optional
4-20 mA output or a high/low flow alarm is available to ensure
reliable operation under all operating conditions.

 RELIABLE
SODIUM HYPOCHLORITE FEEDING
Unaffected by out-gassing or ait-binding concerns that could
be a problem for conventional metering pumps.
INTEGRAL
FLOWMETER
Direct reading, visual indication of chemical feedrate. Dual
scale rotameter in GPH and LPH. Optional 4-20 mA output is available
for remote indication and recording of feedrate. An alternative
option is a high/low flow alarm that can be used for flow/no-flow
status indication. |
WALL-MOUNTED
CONSTRUCTION
The Panel mounted design saves space and simplifies installation.
Components are mounted at the ideal height for operator convenience.
An easily removable cover provides quick access for any service
requirments.
