cargo monitoring - draught level - ballast - fuel oil - seawater - blackwater - service tanks - healing tanks - grey water, double bottom - fresh water - seawater displaced - lub & gas oil 

Proven track record - installed on 1000's of ships worldwide

Fully Submersible Sensor

Marine classification 'Type' approved

Intrinsically Safe Certified

Meets RFI / EMC immunity Standards

Fully Welded Construction

Seawater, oils and corrosive duties

Unrivalled Overload Tolerance

The Level Transmitter 'Tankstar' series is designed to meet the latest IEC and marine standards. It's rugged construction and design flexibility provide reliable monitoring of liquid levels and pressures in harsh environments. Typically ship's tanks and draught applications where conditions of high overload, shock and corrosion are common.

The maintenance free design containing no active electronic components ensures reliable and trouble free operation - critical in shipboard applications.

The 'Tankstar' has the sensitivity needed to accurately measure shallow tanks but sustains a 50 times overload without damage.

Intelligent Modbus Transmitter

High Performance Dual Mode Liquid Level Transmitter with 4 to 20mA & Modbus output

Advanced signal processing provides an increased operational span and sensitivity compared with conventional capacitive devices, reducing the number of nominal ranges to 4 to cover all tank depths up to 50 meters WG, all with the same high performance levels.

The iCT transmitter body is manufactured from high integrity 316 stainless steel and employs a carefully engineered seal assembly in a choice of materials, which draws upon PSM many years of application experience to provide a fully submersible (IP68) construction capable of withstanding the toughest operating conditions.

2000 Series monitoring and Display systems

The success of the single and multi-channel electronic tank level gauging & monitoring systems has lead to a new generation of versatile products from PSM.       

The series 2000 range of tank monitoring devices offers real flexibility to suit any size and number of tanks in the most cost effective manner. All models from single to multi-channel options are fully compatible with any PSM level transmitters to ensure a 'no hassle' installation.  

Powerful, versatile, simple to apply & cost effective, attributes common to all members of PSM’s new generation of 2000 series. Developing on the capabilities of its highly successful predecessor, the range offers comprehensive display & control facilities to keep you clearly in the picture   

Radar level transmitter

The VG7 High frequency (26 GHz) Radar operates on the same proven principle of the earlier lower frequency 10 GHz FMCW Radars.

Enhanced accuracy Vs Pulse Radar

 The difference in dynamic range between the best pulsed systems and the VG7 is more than 30 dB.  This is equivalent in signal power to a sensitivity that is 1000 times greater.  The larger dynamic range of the VG7 allows more stable detection of liquids with very low dielectric and thus very weak reflections.  Between an dielectric of 2 and a dielectric of 1.2, in an otherwise identical measurement environment, the difference in level is approximately 11.5 dB, which is equivalent to 14 times the power difference on a linear scale.

This rugged design of switch is used throughout the process industries.  It is available with a wide range of flanged or screwed process connections and can have extensions, enabling the probe to reach 3 metres into a tank if required. 

The wetted parts of standard switches are 316 stainless steel but special Halar coated and Hastelloy switches are used for extremely corrosive applications and hygienic probes are available for the food industry.

Ultrasonic Level Transmitter

'THE ULTRAMETER'

The Ultrameter family represents a real advance in the use of ultrasound for non-contact level measurement. It is suitable for both liquids and solids measurement. A highly developed and ultra efficient range of sensors emit a significantly higher power acoustic wave than earlier generation devices, providing enhanced accuracy and resolution and the ability to automatically compensate for and operate reliably in acoustically “noisy” or absorbent atmospheres

'Type Approved' Bilge Alarm / Water Level Switches 

 A compact but rugged bilge water alarm switch for Marine use on vessels of all sizes.  The integral manual checking device conforms to class rules without complicating installation. Siting and mounting is simple requiring only a two bolt fixing and the self draining fully shrouded design prevents interference of operation from obstructions or floating debris.

Due to the extremely harsh environments that this switch is likely to encounter, extensive successful testing was carried out exceeding the environmental testing requirements for Marine Type Approval laid out in IACS Unified requirement E10 and the relevant sections of IEC945  for all Marine Type Approvals.

Tankview for Windows^TM  

For larger ships the Tankview distributed data acquisition and monitoring system can stand-alone or communicate with most ships management computer systems.

Tankview offers the user complete freedom to design the screen presentations to suit the application.

Being Windows based Tankview will also communicate with other Window's applications such as spreadsheets to enable detailed usage tracking and analysis, as well as stock control.
