- Liquid Level & Pressure Transmitters 'Optima' 360 Series
- The Level Transmitter 'Optima' series is designed to meet the latest IEC standards. It's rugged construction and design flexibility provide reliable monitoring of liquid levels in harsh environments, even 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
- The 'Optima' has the sensitivity needed to accurately measure down to very low ranges but sustains a 50 times overload without damage.
Compact 1 inch (25mm) diameter
The series 700 borehole & probe transmitters are designed for applications where access for installation is restricted, such as deep wells or buried storage vessels.
A cost effective two wire, 4 to 20mA gauge pressure transmitter.
A two wire, 4 to 20mA gauge / absolute pressure transmitter offering superb chemical and corrosion resistance.
- 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
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

For larger installations the Tankview distributed data acquisition and monitoring system can stand-alone or communicate with most 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.
The PSM Torflow is an averaging multi-port pitot tube which produces a differential pressure output proportional to the square of the flow. It may be coupled with a differential pressure transmitter to give an electrical signal output, or simply piped to a differential pressure gauge or manometer to give a direct reading of the flow rate.
