MSL600 sludge blanket monitoring

Description
The MSL600 sludge blanket monitor is a microprocessor based system, with an abundant range
of built-in, display, control and alarm features. Easy to use menu driven programming allows
complete configuration of the unit. Local programming is carried out via a membrane keypad.

The principle
The MSL600 uses the sonar principle, with an ultrasonic pulse transmitted under water.
Sophisticated echo processing allows the MSL600 to analyse the pulse of
ultrasound which transmits vertically and reflects from the surface of the sludge blanket.
The system captures the ultrasonic echoes reflected from the blanket interface.
Knowing the speed of sound in the supernatant the depth of the sludge blanket is then
determined from the time of flight of the echo.

The system
The system comprises an ultrasonic transducer and a bridge
mounted control unit. These are specially designed for easy
installation on a clarifier tank bridge using a mounting bracket,
supplied with the system. The system is optimised for use
with clarifiers and thickeners containing municipal and
industrial wastewater treatment sludge. The MSL600 provides a
means of sensing the presence of the sludge blanket and measuring
its depth in the clarifier. It also provides a range of current and
relay outputs to the user for control and alarm purposes.
The bridge mounted MSL600 is a stand alone unit which can also
communicate to an optional remote mounted unit situated off
the clarifier bridge, via an integral radio telemetry link with a 500m
range. The radio telemetry option is made available to cater for
applications both with and without moving bridges, where transmitting
small signals through slip rings or over long distances via expensive
cable runs may be problematic.


Important MSL600 features

Human machine interface
In common with other Solartron
Mobrey control units the MSL600 makes use of the intuitive
Solartron Mobrey Human Machine Interface (HMI).
The user can program and interrogate the system using
the integral keypad and Liquid
Crystal Display (LCD) without the need for regular reference to
the manual.
For the more experienced user the HMI also facilitates rapid
navigation of the menu structure and system parameters.

Self cleaning
A key feature of the MSL600 is
its transducer self cleaning facility.
The system is designed for applications where the transducer
may be mounted in a hostile environment where there is the
likelihood of the transducer becoming coated or otherwise fouled.
