Multilog LX2: Wanhua Chemical

Wanhua Chemical, a global leader in polyurethanes and the world’s largest manufacturer or Methylene Diphenyl Diisocyanate, turnover $60 billion annually and have manufacturing sites all over the world.

When Wanhua Chemical required both pressure and leak noise monitoring for their water network, they turned to HWM for a bespoke solution.

Approaching us with a unique set of requirements, Wanhua Chemical needed accurate monitoring of both the pressure within their water network and leak noise to identify leaking pipes.

To be able to meet these specific requirements we combined our Multilog LX2 datalogger with a Hydrophone sensor.  The Hydrophone is able to monitor both pressure and leak noise, while the Multilog LX2 device records the data and uses both 3G and GPRS transmission to provide Wanhua Chemical with the recorded information.

Wanhua Chemical are the first company to use the combination of Multilog LX2 and Hydrophone to monitor both pressure and leak noise.  Successfully installing 42 loggers now allows Wanhua Chemical to completely monitor their water network at one of their main manufacturing sites.

Throughout the trail and installation process HWM has offered regular support to Wanhua Chemical, including weekly meetings to discuss the status of the project.

HWM have also been able to support in choosing locations within the network for the loggers to be placed.  One logger was found to be picking up external noise after installation which was resulting in false leak readings, but this was quickly rectified during these regular support meetings and results are now more accurate as a result.

With ongoing support from us at HWM, Wanhua Chemical will continue to successfully monitor their water network using the innovative combination of Multilog LX2 and Hydrophone.
