• Metering pump shows versatility  

  WANNER says to call its new Hydra-Cell MT8 a low flow high pressure metering pump would do it a serious injustice. The company says this amazing triplex diaphragm pump can achieve a minimum flow rate of 0.227 litres per hour with the accuracy, linearity and repeatability demanded by API 675, but is capable of generating a maximum flow of 30.28 lph. The Hydra-Cell MT8 is designed to perform at pressures, up to 241 bar, while generating a smooth virtually pulse-less flow for homogeneous metered injection.

• Compressed air pressure dew point monitoring 

  On-site compressed air pressure dew point monitoring is now said to be accurate and easy with the S505 handheld tester from SUTO-iTEC GmbH and MEASURE MONITOR CONTROL. The results can be read straight from the screen and the S505 measures pressure dew point directly through internal pressure and dew point sensors, removing the need for calculations or correlating readings, saving time for more tests.
