Canongate Technology Ltd based in Edinburgh will be launching its enhanced VesselCheck ST1A on stand D10 at AEGPL 2009 in Vienna on May 13-15. The company has been using ultrasound technology in a variety of applications for over twenty years. The VesselCheck ST1A tank level monitor has been specifically designed to meet the requirements of lpg vessels and a number of leading lp gas suppliers are already using the technology, says Iain Crolla, internal sales and marketing manager at the company.
A small ultrasound transceiver is bonded to the outside shell of the vessel using specific industrial strength adhesives. The ST1A transmitter then uses echo-sounding technology to calculate the time taken for the transmitted ultrasonic signal to return to the transceiver from the surface of the liquid lpg gas. The transmitter temperature compensates the signal and calculates the liquid height from the transit time. The height is then output as an analogue or digital signal for display and/or use by other supervisory systems.
The VesselCheck ST1A’s new features include enhanced compensation for temperature variations, an ATEX approved display option, battery powered versions, a low power consumption feature and several new output options. “Quality of product and service is regarded as a priority within Canongate,” said Iain. “We have adopted the principles of Total Quality Management in all our activities, and welcome visits to our factory for assessment of our capability at first hand.
“The benefits of non-invasive level gauging are well established and they are just as relevant for the VesselCheck ST1A. There is no interruption during installation as sensors are bonded to the external wall of the lpg vessel; maintenance is easy as everything is external to the vessel, it can be easily programmed for most vessels and the cost of purchase and ownership is low.”
