Description

The FLOMEC QS200 Ultrasonic and Badger Meter Impeller flow sensors are both PVC tee insert-style meters designed for agricultural irrigation, but they differ slightly in sensing technology and maintenance needs. The FLOMEC QS200 uses ultrasonic measurement, offering low-flow detection, no moving parts, and reliable performance even in compressed-air winterization, making it a durable alternative for paddlewheel sensors. In contrast, the Badger Meter Impeller employs a six-bladed non-magnetic impeller with a built-in preamplifier, delivering strong torque, repeatable operation, and long-distance signal transmission, though it requires periodic servicing of its mechanical components. Both models fit standard PVC tees and provide accurate flow monitoring.

Wiring

FLOMEC or Badger Meter	Verdi Sensor Adapter
Black wire connects to →	GND (Pin 1 or Pin 3)
Red wire connects to →	S1 (Pin 4)

Note: add a jumper wire to connect pin 4 and 5

Route the cable from the sensor to a Badger Meter flow monitor/endpoint . The cable may be extended up to 2000 feet (610 meters), using 2-conductor shielded 20 AWG (or larger) stranded copper wire. Be sure to leave enough flexibility in the cable or conduit to allow for future service of the sensor.
