Sludge blanket level
Ametek Drexelbrook’s CCS4000™ Multi–Channel Sludge Blanket Level Monitor uses a field proven algorithm to keep track of effluent quality in up to four separate water and wastewater treatment clarifiers and thickeners. The system uses advanced ultrasonic technology to measure the compacted sludge level, the lighter rag material above the interface, and clarity loss in the water above the blanket and rag levels. It eliminates worry about the adverse effects of denitrification, septic sludge, washouts, and mechanical breakdown of a rake.

Tank level sensor
Red Valve’s Series 40TL Tank Level Sensors are specifically designed for sensing level in storage tanks. The sensors are not affected by foaming, ice and other conditions that can cause errors in ultrasonic and capacitance level sensors. They use a high–sensitivity, solid–state pressure transmitter that is completely isolated from the process fluid by an elastomer sleeve that transmits pressure through a fluid bill.

Pump flow monitor
Digi–Pulse Flow Monitors are designed to be used with the LMI Milton Roy Type “9” Metering Pumps to provide the user with verification of pump performance. If the flow monitor detects output loss, it will shut the pump off and close a switch that may be tied to an alarm. The alarm signal may also be used to trigger a stand–by pump. This inexpensive device provides valuable data about the operating condition of the pumping system overall and the pump in particular.

Ultrasonic level measurement
Emerson Process Management is offering a new version of its Mobrey® MSP900 ultrasonic level transmitter, optimized for use in open channel flow measurement. Used in the open air, conventional ultrasonic level transmitters are prone to suffer from inaccuracies caused by “solar gain” when the sun shines directly on them. The new transmitter has been designed to overcome this problem by using a remote temperature sensor wired directly into the transmitter.

Automata’s Laser Level–Watch sensor is a light beam time–of–travel device. Velocity of light is constant; not affected by temperature or any other environmental conditions. The accuracy is limited only by the quality of the electronics in the laser range finder. There are no moving parts to wear out so maintenance is kept at a minimum. A stilling well is needed to keep the travel path for the light beam unobstructed during inclement weather.
