Flow meter reference design

19 November 2014 Design Automation

Utilities can improve water- and heat-metering accuracy while operating for up to 20 years on a single A-size battery with the MAXREFDES70# ultrasonic flow meter reference design from Maxim Integrated Products.

Traditional mechanical flow meters measure water and heat usage with spinning wheels that easily get out of calibration due to wear from friction and contaminants. This causes inaccurate meter readings and repeated, expensive on-site maintenance costs. Not only do these inaccurate readings reduce revenue, they also prevent leak detection, potentially wasting millions of litres of clean water a year.

The MAXREFDES70# ultrasonic flow meter is the modern alternative to that old technology. Measuring as little as 0,5 litres of water per minute with better than 1% accuracy, its fast ultrasonic pulses can be customised to the pulse frequencies required by flow conditions. It can detect even minor leaks that mechanical meters will never find.

At the heart of the reference design is the MAX35101, a complete time-to-digital converter with analog front-end (AFE) that measures the difference of upstream and downstream ultrasonic pulses. Supporting flow measurement at low rates (< 30 l/hr), the chip offers conversion accuracy of 20 ps.
