PRODUCT OVERVIEW
Monitrol is a turn-key fluid control system including a globe
style control valve, a variety of BUILT IN SENSORS FOR FLOW,
PRESSURE AND TEMPERATURE, a High Precision Electric
Actuator, along with control logic and an easy to use TOUCH
SCREEN INTERFACE. Monitrol can manage up to three variables
(sensors), simultaneously with its control logic. FLEXIBILITY allows
the control logic in Monitrol to be bypassed if that is desired. A
Building Management System can still maintain all control and
just make use of the sensor information if that is desired. A full
range of I/O signals, feedback and communications including
modbus, ethernet & wifi are available.
FLOW REGULATOR
There are two distinctly different versions with differing
technologies. One serves as a very accurate flow metering flow
control valve. The other provides reasonably accurate information
about flow to a Building Management System (BMS) for monitoring
load control decision making.
MAG-FLOW VALVE - This version of the product has a Magnetic
Flow Meter and flow straightening tube as integral parts of the
Monitrol assembly. Flow control accuracy is specified at ±0.5%.
SIZES 2 - 12 INCH

VARI-ORIFICE DP VALVE - This version of the product uses a lower
cost method of Flow Calculation with differential pressure and the
know Cv of the valve and specific gravity of the controlled fluid to
calculate flow. Flow control accuracy is specified at ±1.6%.
TEMPERATURE REGULATOR
With the inclusive remote temperature sensor, you can control
the temperature of a secondary flow stream with the Monitrol
installed on the primary flow stream. An example might be with
the Monitrol connected to a heat exchanger where it is desired to
maintain a constant outlet temperature.
PRESSURE REGULATOR
With a built in Pressure sensor, you can control the up-stream
pressure of the flow stream (Back-Pressure Regulator), or down-
stream pressure of the flow stream (traditional PRV).
Each valve has two pressure taps upstream or down stream for
this function. Incredibly accurate pressure control with a full range
of set points under all load conditions is the result.
