Abstract
Water has always been the source of growth and dispute between providers and
consumers. Nowadays, water conservation and environmentally friendly
technologies are becoming more important, especially in areas where access to
water is expensive or restricted. Since water has become a limiting resource for
economic development, accurate measurement of consumption is important for
both trade and industry. Unfortunately, over time and use, the internal
components of a measuring flow meter wear, and the level of metering accuracy
drops. This progressive drop in metering accuracy causes \“meter drift”.
This paper studies the effect of drift/errors in flow meters used in seawater
pumping stations, which are supplying seawater for several refineries and
petrochemical plants in Kuwait. The seawater pumped to these consumers is
utilised for cooling and process purposes. In such high volume consumer system,
a small drift may result in lost revenue due to an under-accounting of the
quantity of used water. In such systems, in order to endlessly repair, rebuild or
recalibrate all the flow meters a labour intensive and expensive process is
required that causes significant down-time too. In the presented research work, a
novel mathematical method is presented which provides early detection of flowmeter
drift irrespective of type (ultrasonic, magnetic, etc.). This method is
designed based on the mathematical models of the system and its process
relations. The proposed method works with minimal input data and provides an
inexpensive solution to existing measuring systems.
Keywords: flow meter, flow meter drift, data analysis, statistical process control
(SPC).
