1 Flow measurement CHANFLO 2500 / 3000 Open Channel Flowmeters DCHANUS0108

2 General measures the flow rate of water or wastewater in all types of weirs and flumes and provides a display of both current flow rate and totalized flow. can be used with either ultrasonic or hydrostatic level sensors. Features Available with either SONOLEV 1100, PRESLEV 3100 Hydrostatic Level Transmitter or for 4-20 ma input. High measuring accuracy in ranges from 0 to 4 in. to 0 to 3 ft. The Flowmeter is calibrated from the front panel. Easy to operate with user dialogue in English or Spanish. Security access code prevents altering of settings and readout of recorded data. Backlit 2-line 48-character LCD display. No loss of data from power interruption as all values are stored in EEPROM. Indicates actual flow and average flow for the last hour, today and previous day. Totalizer for the last hour, today and 99 previous days. Alarms can be set for system failure, high and low flow and high volumes. Built-in power monitoring. Power failures are registered in the alarm log. Application is commonly used for flow measurement in municipal and industrial sewage treatment plants, in fish farms and for flow measurement in streams and rivers. Function linearizes the signal from the sensor making it proportional to the flow rate by calculating the flow using one of the following methods: - preprogrammed formulas for the most commonly used flumes and weirs, such as Parshall or Palmer-Bowlus flumes, V- notch weirs and rectangular weirs - when using other flumes or weirs not preprogrammed, the exponent and factor for those primary devices may be entered to allow accurate measurement, e.g. Cipoletti weirs. - for flumes where no formula exists, a number of Q/h-values can be entered from which linearization is calculated Sensors SONOLEV 1100 Suitable for narrow channels; only 3 beam angle. High resolution and accuracy from 4 in to 10 ft. Easily adaptable to any weir or flume with standard mountings. Ex-approved. PRESLEV 3100 Hydrostatic Level Transmitter Rugged construction with excellent stability. Standard 1 NPT threaded for pipe mounting. Easy to install in stilling wells. 2

5 How the CHANFLO TM flowmeter works The CHANFLO works by measuring flow in flumes or weirs. The CHANFLO measures the depth of flow in the primary device and calculates the flow rate based on the standard curve for the primary device used. This is typically based on the equation: FLOW Q = level x * constant The exponent ( X ) and constant depends on the type of primary device used. A pre-programmed list of standard weirs and flumes allows easy selection of the equation required for the primary device, however a custom curve can be configured for non-standard primary devices. The CHANFLO is easily programmed via just 4 function keys: Flow Key, Totalizer Key, Alarm Key and the Sampler Key. The function keys allows access to the various parameters shown below: Flow key: actual flow rate average flow rate - over last hour - today - previous day Totalizer key: total flow - since startup - over last hour - today - previous day - any previous day up to 99 days back Alarm key: displays last 9 alarms with date and time stamp - sensor errors - high and low flow alarms - high and low hourly flows - high and low flow for day - power failure Sampler key: total samples total samples today total samples previous day 5

6 Flumes For measurement of waterflow in open channels we can supply a series of prefabricated flumes. Parshall and Palmer & Bowlus flumes are made according to ASTM standards.
