  • Electrodes

    Electrodes

    Electrodes are at the heart of our Hydrastep & Hydratect system.

    As well as being essential to the measurement of water and steam, they are also incredibly durable and reliable.

    This is due to their specific design, as each electrode is handcrafted and tested to withstand both extreme pressures and temperatures. As a result they can endure harsh conditions for many years (even decades), ensuring that your plant will continue to operate safely and consistently.

    For use with Hydrastep & Hydratect
  • Boiler Water Level Controls

    Boiler Water Level Controls

    Boiler Water Level Controls

    This family of Boiler Water Level Controls are designed to regulate the flow of feed water into the boiler in proportion to the steam demand by using the change in boiler level as a load indicator. They consist of the following elements:

    Modulating Controller:

    The Delta Mobrey Modulating Controller is a single element electro-hydraulic control with an electronic feedback, used for controlling the flow of feed water into the boiler. Designed to be used alongside the Delta Mobrey
    Vertical Air Break Controls (VABC).

    Sequencing blowdown valves:

    The Delta Mobrey sequencing valve is designed to function as a combined water isolating valve and a sequencing blowdown valve to provide positive purging of the water connection, float chamber and steam connection of a boiler control. The operation of the valve helps to ensure the water port does not become blocked by sediment, mud or debris. It also provides a positive test of the boiler water level control, ensuring that any associated equipment, such as the feedwater pump or valve, and any alarms, cutouts or lockouts operate as expected.

    Vertical Air Break Controls

    The Delta Mobrey Vertical Air Break Controls (VABC) are a comprehensive range of magnetically operated water level controls for steam boilers. They are designed to meet all requirements for automatic on/off control of boiler feed pump, burner cut out, high and/or low level alarm or any combination of these. Models available with Industrial (NEMA4) or Marine Heads. TÜV approved models are available in chambers and for direct mounting. The Delta Mobrey VABC is a gland-less construction. A primary permanent magnet is attached to the float rod and slides vertically inside a non-magnetic stainless steel centre tube. Movements of the float are transmitted to a secondary magnet in each switch unit.

  • MSM400

    Suspended Solids Monitoring – MSM400

    Suspended 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. View our webinar featuring the MSM400.

  • Hydratect 2462 System

    Hydratect 2462 System

    Hydratect 2462 System

    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 the safe and efficient operation of a plant. 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 which 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 which are fitted into inserts which are welded into the pipe work. Alternatively, manifolds can be supplied to drawing 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.

  • Hydrastep 2468 System

    Hydrastep 2468 System

    The Hydrastep 2468 is the modern day equivalent of the site glass to monitor, display and measure the output level of the water/steam interface. For use on water tube boiler steam drums and de-aerators, the Hydrastep name has become synonymous with steam drum level measurement, and through its evolution has ensured plant safety globally for more than five decades. Assessed by an external body and found to be SIL 2 capable, according to the requirements of IEC 61508. It is recognised by boiler inspectors and plant insurers, the ASME approved design ensures Hydrastep can be used as a Remote Level Indicator in compliance with ASME Boiler Code PG60.1.1. It is also approved by Factory Mutual for boiler level control and recommended within the UK’s Combustion Engineering Association’s water tube boiler guide BG11. All of this expertise is backed up by over 6000 installations of Hydrastep around the globe. For more information on this product view our webinar on Hydrastep’s involvement in the boiler industry!
