The Flo-System Model 253 Open Channel Flowmeter is your most cost effective solution for the accurate measurement of open channel flows in round, rectangular, oval and egg shaped conduits. The Model 253 does not require additional costs for site construction/modification of primary devices such as weirs or flumes.

Ideal applications include:

‧Inflow/Infiltration Studies
‧EPA Permit Applications
‧Chemical Laden Flows
‧Storm Water Management
‧Billing Purposes
‧Industrial Flow Processes
‧Combined Sewer Overflows

Advantages

‧Does not require expensive primary devices such as weirs or flumes.
‧Accuracy is maintained even in surcharge conditions.
‧Capable of measuring reverse flows.
‧Measures both velocity and depth which are absolutely necessary for the accurate 
determination of flow rate over wide flow ranges.
‧Proven electromagnetic sensor technology based on Faraday’s Law for superior 
accuracy and reliability.
‧Non-fouling and more robust electromagnetic sensor.
‧Q-Stick™ band/sensor installation tool for above ground, no manhole entry installations.
‧Wide sensor installation bands for increased accuracy in debris laden flows.
‧Compatible with sampler of your choice.
‧No Site Calibration required with new Auto-Cal feature.
‧ATC Level feature eliminates temperature induced level errors.
‧Intrinsically Safe version now available.
