Sundyne HMD Kontro Vapour View Condition Monitoring

VapourView Solution Early detection of gas within the process liquid is critical to eliminate the risk potential and the patented VapourView uses ultrasonic technology to achieve this. The VapourView instrument provides vital information to the end-user on the presence of gases in the pumps internal flow regime and forewarns of adverse conditions. Early intervention by system engineers, who can undertake remedial action, will thereby maximise the operating life of plant equipment. How it Works The presence of gas in a liquid greatly affects the transmission of ultrasound in two ways. For larger bubbles and gas pockets the dissimilarity in acoustic impedance between the gas and surrounding liquid causes scattering of the sound wave. Smaller amounts of gas entrained within the liquid cause attenuation through absorption. By sending an ultrasonic wave through the process liquid and measuring the drop in signal amplitude due to these effects, the presence of gas can be detected. VapourView is powered by an industry standard 24 Vdc supply and returns a 4-20 mA signal suitable for monitoring using a distributed control system (DCS). It features both light emitting diode (LED) and liquid crystal displays (LCD) to provide on-instrument information, on system conditions to Service Personnel in attendance. The VapourView instrument has been performance tested and is compliant with explosive atmosphere and electro-magnetic compatibility requirements. VapourView is available for use on GSP and GSA pump ranges, frame sizes 1, 2 and 3. It is retrofitable to these pump types and will operate at temperatures between -40 and +180 Celsius (-40 and +350 F). Benefits Complete sealless pump security No potential for dry running Ensures correct priming and venting Improved and consistent reliability Prevents catastrophic failure No unexpected repair costs Reduced cost of ownership Increased process and profitability Adaptable for many applications Suitable for hazardous environments Compatible with existing systems Complies with relevant standards
