KROHNE helps control trade effluent costs

A world-leading ingredients manufacturer has installed KROHNE?s electromagnetic flowmeters to measure more precisely the volume of effluent discharged from its plant so it can control water utility costs more accurately.

Companies can lose tens of thousands of pounds a year through inaccurate measurement of trade effluent which is pumped into sewers and charged for by utility companies.

The ingredients manufacturer?s production plant operates 24 hours per day, 365 days per year.  The effluent discharged by the plant can average 33,000 cubic metres per month.

Previously the company used ultrasonic level in conjunction with a classic flume to measure effluent discharge. However, these devices do not give a direct measure of flow and can result in a +/- 3 ? 5 per cent error in reading ? equating to a difference of 1,500 cubic metres per month.

The ingredients manufacturer has now installed two electromagnetic flowmeters from its preferred supplier KROHNE, which improve measurement accuracy significantly.  The instruments are accurate to +/- 0.3 per cent ? equating to just 11 cubic metres per month.

?Using KROHNE?s flowmeters has improved significantly how accurately this company measures trade effluent,? said Chris Ringer, sales manager for KROHNE.  ?Previously it used ultrasonic level but, given the volume of effluent that was generated and their low accuracy, the company could have been paying utility bills that are substantially different from the actual volume of effluent generated ? and they would have never known that.

?By installing KROHNE?s electromagnetic flowmeters the company can now more accurately control its water utility costs.?
KROHNE?s flowmeters are installed in-line with the effluent discharge feeds.  They consist of a primary head, which is installed in the pipeline itself, and a signal converter that is mounted on top of the primary head.
