The investment pays dividends: <strong>30-45%<\/strong> reduction in water loss and <strong>200-400%<\/strong> return on investment are achievable for committed utilities.<\/p>\n<p>ChiMay&rsquo;s flow meters and sensors\u2014including turbine flow meters, paddle wheel flow meters, and inline conductivity meters\u2014provide the measurement foundation for effective leak detection programs.<\/p>\n<p>Water is precious. Every liter lost through undetected leaks represents wasted resources, energy, and infrastructure investment.
