Global Water's FC220 Open Channel Flow Monitor is a reliable and accurate instrument for measuring and totalizing open channel flows for all flumes and weirs, as well as for any gravity-type open-channel flow application. The flow meter measures water depth using any 4-20mA water level sensor's output including all Global Water's submersible pressure transducer or ultrasonic water level sensor and the flow meter's powerful microprocessor instantly calculates and displays water flow and totalizer values in user selectable units using one of several water flow calculation modes. The Open Channel Flow Monitors have an 8-button keypad that easily guides you through the versatile setup menus.
For any open channel that is free flowing, there is a specific relationship between depth of water and flow rate. Whenever a given depth occurs, there will always be the same water flow. Therefore, if the flow rate is known for each depth, a depth-to-flow relationship can be constructed. The Open Channel Flow Monitor supports a large number of different types of flow calculation modes. Over 40 preprogrammed flume and weir tables are included with the open channel flow meter. For monitoring in round pipes and open rectangular channels; the water flow meter's Manning's Equation mode allows the user to enter their own parameters for material, slope and pipe or channel dimensions. The open channel flow monitors also allow you to define standard flow equations, which can calculate flow for almost all flumes and weirs.
NOTE: To complete your open channel flow monitoring system, a submersible pressure transducer or non-contact ultrasonic liquid level transmitter is required. Also, cable length between the transmitter and open channel flow meter must be determined prior to completing an order.
The FC220 can be supplied with an external data logger to record flow rate and total flow. Choose your water level transmitter from one of the options below.
Open Channel Flow With Senix Ultrasonic Water Level Transmiiter
Open Channel Flow measurement determines the volume of water, effluent or industrial waste flowing through a channel, flume or weir. Flumes and weirs are hydraulic structures within which the liquid flow rate is determined by measuring the height of the liquid flowing through the structure. That height is converted to flow using an equation specific to the structure. Positioned at the required location, ToughSonic sensors measure the liquid height by non-contact distance measurement looking down at the liquid surface.
FL400 Submersible Flow Sensor
The FL-400 is a Flow, Depth, and Temperature sensor for sewer and drainage pipes and other open channel applications like flumes, weirs, and square channels. The specially engineered, non-fouling water level sensor works in depths as little as ½ inch. It allows deployment in maintenance holes and other difficult-to-access areas without entering the confined space.
KELLER’s NANOLEVEL Submersible Water Level Sensor
The Nanolevel submersible level transmitter utilizes a ceramic measuring cell for high resolution and excellent stability in applications with very low pressure ranges. The dual output feature ensures compatibility with most pump controllers and SCADA systems.
WL400 Water Level Sensor
Global Water's standard open channel flow monitors can measure flow depth with any 4-20 mA water level sensor including the highly-accurate WL400 Water Level Sensor, which is a fully submersible water level sensor constructed of stainless steel. Any water level sensor range can be used with the flow meter, however a sensor with a range near to your largest expected water level change will give you the best accuracy. Submersible pressure transducers should be mounted slightly below the "zero" flow depth of the open channel, upstream from the throat of the flume or weir. For open channels with no primary device, the sensor should be mounted below the lowest expected water depth. Because the open channel flow monitor accepts a 4-20 mA input signal it can be mounted up to 3000 feet away from the water level sensor.
