10 Water / Wastewater Small yet Accurate SVP Launched


Production is now underway on Valeport’s (UK) latest innovation - the new UV-SVP - a small and compact direct reading package aimed primarily at AUV and ROV users, which delivers high accuracy data to compliment survey work.


Valeport’s UV-SVP (Underwater Vehicle – Sound Velocity Profiler) is based on the company’s miniSVS and offers a form factor designed for underwater vehicles where space is at a premium.


Measuring sound velocity, temperature and pressure, the UV-SVP uses Valeport’s class leading time of flight sound speed sensor, a PRT temperature sensor and a 0.01% accuracy pressure transducer in a compact package weighing just 750g in air. The lightweight titanium housing gives a depth rating to 3000m as standard. A wide range (9-30v DC) isolated power supply and RS232 communications complete the package.


Valeport, the UK’s leading manufacturer of oceanographic and hydrographic instrumentation, designed and manufactured the UV-SVP at their state of the art facilities based in the UK.


Developed in response to a specific customer requirement, the UV-SVP has already been adopted by Bluefin Robotics for integration into the Bluefin 9 AUV. With a reputation for supplying the world’s most accurate sound velocity sensors, Valeport believes there will be strong demand for their small, lightweight and accurate UV-SVP as the AUV market sector continues to grow rapidly.


Kevin Edwards, Valeport sales and marketing manager commented: “The UV-SVP draws upon our existing technology and expertise. Initial feedback we’ve received to the new gauge has been very positive. Recent industry research indicates the AUV market is rapidly growing across all sectors and we believe this poses significant opportunities for space-efficient and accurate sensor instrumentation.”


With an established reputation for high quality, reliable and innovative instrumentation, the UV-SVP, - like all Valeport products - ,benefits from an industry-leading three-year warranty.


Valeport also offers a unique 12-month warranty on all their serviced products as well as a dedicated calibration and service facility. Rapid Test Catalogue

Valveless Methanol Metering Pump for Wastewater Denitrification


For small and mid-size treatment facilities, US based Fluid Metering, Inc’s (FMI,) valveless QDX metering pump is the answer for low volume addition of methanol for nitrate removal in wastewater effluent.


The release of high nitrogen concentrations of wastewater effluent into bays and watersheds is of great environmental concern as it can have a devastating effect on water ecosystems. Through a process known as “denitrification”, water treatment facilities convert the excess nitrate into nitrogen gas, which is then vented into the atmosphere.


The CeramPump QDX Hazardous Duty Metering Pump from Fluid Metering has proven to be an excellent choice for methanol metering for waste water denitrification due to its unique valveless design. This is especially applicable in small to mid-size treatment facilities where flow rates are extremely low causing valved pump designs to become air-bound and lose prime.


The CeramPump has only one moving part in contact with the process fluid, a rotating and reciprocating ceramic piston. Similar to conventional piston pumps, the piston’s reciprocation performs the


pumping function. However, this is where the similarity to conventional piston pumps ends.


The piston simultaneously rotates during the pumping cycle and is synchronised to alternately open and close the inlet and outlet ports of the pump effectively functioning as a valve. At no point are the inlet and out ports interconnected, thus eliminating the need for check valves. The pump drive is FMI’s QDX Hazardous Duty Drive, typically required for pumping methanol.


For over 50 years Fluid Metering’s pumps have been used for precision fluid control in chemical process, pharmaceutical manufacturing, mining, water & wastewater treatment, environmental monitoring, and food processing, as well as medical and analytical instrumentation.
