The same is also available for the controls of liquids, in combination with the Ultrasonic series 003 and all the mechanical float types.

The vibrating forks are energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics, which switch the output relay after a configurable time delay. The vibrating fork level switch is the perfect solution for single point level switching in free flowing solids and liquids across a wide density range, covering all the needs from industrial applications to the compactness requirements typical of the applications on machines.

Key Features

• Configurable action
• Threaded or flanged connection
• Side or top mounting
• Compact and mini construction available
• Robust aluminium housing
• IP67 ingress protection
• AC or DC supply voltages
• ATEX approved

All models have a large LCD display with push button menu driven programming. Options are available for data logging, with download facility. The DMCU900 provides an intrinsically safe power supply for I.S. transmitters.  The wall mount model has a protective hinged lid with clear visibility of the display.

The DMCU900 series provides full functionality for configuration and diagnostics of any Delta Mobrey HART ultrasonic transmitter.

This product, when used in conjunction with Detla Mobrey Ultrasonic level transmitters, can be used to display the level or volume of linear or non-linear tanks, measure open flow for many weirs and flume designs as well as giving high or low alarms for storage tanks.

Key Features

• Controller for use with DMSP400, DMSP500 and DMSP900 series level transmitters via HART comms
• Display measured values, control pumps, actuators and alarms
• Configure Delta Mobrey HART transmitters, access diagnostics
• Single or dual transmitter inputs
• 4-20mA and up to five relay outputs
• Data logging option with SD card slot and RS485 comms
• DC or AC power supply
• Galvanically isolated supply to power Intrinsically Safe transmitters

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.

The vibrating rod is energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics which switch the output relay after a configurable time delay. The vibrating rod level switch is the perfect solution for single point level switching in free flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged.

Key Features

• Adjustable sensitivity
• 1 ½” BSP or NPT threaded connection
• Side or top mounting
• Extension lengths to 20m
• Robust aluminium housing
• IP67 ingress protection
• AC or DC supply voltages
• Dust explosion protection
• High temperature option
