Insertion Flow Sensors220 Series

• 220 Series sensors are specifically designed for installation in underground vaults that might be subjected to flooding.
  As the liquid flow turns the impeller, a low impedance 8V DC square wave signal is transmitted with a frequency
  proportional to the flow rate. This signal can travel up to 2,000 feet between the sensor and the display unit
  without the need for amplification. 

Features

• Six-bladed impeller design with a proprietary, non-magnetic sensing mechanism
• Sensor electronics easily removed from tee
• Two-wire sensor—power and signal transmit on a single pair of wires up to the distance of 2000 feet 
• Flow indicators are configured with two 48 inch single conductor leads
• Digital signal easily interfaced with transmitters, monitors, or PLCs

Specifications

• Size : 3 - 40 in.
  
• Accuracy : ±1 %
• Temperature : Up to 221 °F
• Flow Range : 0.3 - 30 ft/sece
• Pressure Range : Up to 400 PSI

Benefits

• Cost savings over other systems offered on the market today
• Impeller, bearing and shaft are easily replaced in field without changing calibration
• Impeller shape coupled with the absence of magnetic drag provides accuracy and repeatability
