LOW FLOW METERING SYSTEM DESIGN
(716) 773-6872 x203
An inactive rural landfill site with no readily available electrical power system and a low rate of gravity leachate flow was required by the regulating authority to install a continuous flow monitoring system. DE was retained to design a flow metering system capable of measuring and recording instantaneous flowrates and totalized flow values.
DE services included:
Evaluation of low flow metering technologies (area velocity, ultrasonic, electromagnetic, digital paddlewheel), and selection of the most appropriate and economical system;
Reconfiguration of the existing leachate drain to re-route flow to a large 60° V trapezoidal flume and ultrasonic open channel flow level sensor;
Sizing of a solar power and battery backup system capable of energizing the metering system and withstanding harsh winter conditions;
Preparation of permit applications and construction documents;
Construction Quality Assurance during the site infrastructure modifications and flow metering/solar power system installation;
Operation and Maintenance Manual tailored for use by field personnel for maintenance, repair, calibration, and flow data collection; and,
Construction Certification Report and drawings for regulatory review.
