Flow Monitoring

 

EST has experienced pipeline technicians on staff and the state-of-the-art equipment necessary to generate accurate and reliable continuous flow monitoring data. Our extensive inventory of open channel flowmeters collects depth and velocity data and are capable of measuring surcharge flow conditions. EST maintains and calibrates their flowmeters routinely to ensure the devices remain in proper working order. EST can also install flow monitoring units with telemetry to facilitate 24/7 access to monitoring data and alarming during overflow (or other) conditions. After data collection, our final reports include equipment installation records, field calibration records, and detailed flow monitoring data, which are provided in various user-friendly formats.

Over the past five years, EST has installed several hundreds of temporary or permanent flow monitoring systems, in more than 150 municipalities, throughout the Northeast. These continuous flow monitoring systems have been used to measure wastewater flows in conjunction with numerous inflow/infiltration investigations, capacity studies, Combined Sewer Overflow (CSO) monitoring programs, and municipal billing programs.

EST has a strong commitment to safety. Our OSHA-40 certified flow monitoring technicians are confined space entry certified and when working in active thoroughfares, we provide appropriate temporary traffic control measures to enhance the safety of motorists, pedestrians, and our workers. In addition to safety, it is our goal to perform our work in a manner which minimizes the disruption of pedestrian and vehicular traffic.
