Suspended Solids Monitoring – MSM400
On/Off and continuous monitoring of suspended solidsSuspended Solids Monitoring – MSM400
The Delta Mobrey MSM400 system continuously measures the suspended solids within sludges or slurries. Many years of practical experience have shown that measurement of ultrasonic attenuation in a slurry is directly proportional to the percentage of suspended solids. The MSM400 system uses this principle to give a digital display and continuous output of the suspended solids measurement.
Commonly used in waste water treatment, industrial and mining plants and suitable for a wide range of fluids such as effluent, limestone slurry and China clay. Applications include sludge blanket measurement and detection, and slurry density control. The MSM400 controller is used with ultrasonic gap sensors available for either tank or pipe installation with a range of gap sizes to suit the application.

Hydratect 2462 System
Conductivity Probe Steam and Water DetectionHydratect 2462 System
Hydrotect is an electronic alternative to conventional water level switches for steam-raising plants. Hydratect can be used in a wide variety of situations, wherever the detection of water or steam is vital for a plant’s safe and efficient operation.
The Hydratect 2462 control unit provides signal processing for two electrodes. Each channel monitors the status of its associated electrode. Four conductors are used between the control unit and each electrode so it can differentiate between steam, water, short-circuit, and open-circuit. A green LED indicates water, a red LED indicates steam and an amber LED indicates a fault condition. Each channel has a status relay to indicate water or steam, and a fault relay that will de-energise on a fault condition. The two channels are completely independent having separate power supplies, signal processing, and fault detection. The relay outputs can be externally wired for a ‘one out of two’ or ‘two out of two’ tripping scheme.
A Hydratect 2462 system consists of electrodes fitted into inserts and welded into the pipe work. Alternatively, manifolds can be supplied to technical drawings with inserts already in place. Electrodes are protected by covers. A military specification high-temperature cable connects each electrode to the Hydratect control unit.
A typical application to ensure TWIP (Turbine Water Induction Protection) is condensate level detection in drain pots (condensate pots).
Hydratect can be used to give compliance with ASME TDP-1, Prevention of Water Damage to Steam Turbines Used for Electric Power Generation: Fossil-Fuelled Plants.
