The OCM III open channel flow meter from Siemens-Milltronics is a high accuracy non-contact ultrasonic flow monitor for open channels to complete system studies. In addition to monitoring flowrate in sewage works, the OCM III can monitor industrial discharge, rainfall/storm water studies, inflow/infiltration studies, and sewer system evaluations. The programmable head versus flow curve (up to 16 points) accurately defines flow rate on unique or non-standard weirs and flumes. Where such a structure is not feasible, the OCM III can be used with the VS 100 velocity sensor.
The OCM III flow meter has data logging and is adjustable from once per minute to once a day. It records the average flow rate for that time period. Daily, it records min/max of temperature and flow rates, and the time they occurred, as well as the daily total. Advanced functions include variable rate logging. It can be pre-programmed to log at a higher rate when needed. Under steady conditions, the OCM III automatically logs less frequently to conserve data log space.
The OCM III open channel flowmeter has two-way communication via RS-232 with a modem or a bi-polar current loop with a current-to-voltage communication converter. Data logs can be downloaded to a file that can be manipulated into a spreadsheet or ASCII format.
The Siemens OCM III Open Channel Flow Meter is now MCERTS certified meeting the Environment Agency's performance requirements. View downloads for certificate.
