Model BFM Series - Irrigation Flow Meters

Flow biCoders™

Features

• The Flow biCoder has true two-way communication using a 9-byte packet for commands and replies.
• The Flow biCoder is capable of self-identifying to the two-wire controller and will report pre-configured unique serial numbers and zone addresses.
• The Flow biCoder serial number is printed on the side of the decoder.
• Each Flow biCoder has 24 inches of 16-gauge PVC jacketed solid core wire to connect to the two-wire.
• Each Flow biCoder has 24 inches of 18-gauge PVC jacketed stranded core wire to connect to a pulse output flow meter.
• The Flow biCoder can be connected to flow devices with either 2 or 3 wires.
• The Flow biCoder has collision detection on the two-wire and is able to resend messages if a collision is detected.
• The Flow biCoder reads a minimum of a 5-millisecond low pulse at 200 hertz and a maximum of 200 pulses per second.
• The Flow biCoder is able to search for a flow meter.
• The Flow biCoder is able to run a pulse-output flow meter up to 1000 feet away.
• The Flow biCoder has a built-in amperage meter to accurately measure and diagnose flow meter electrical problems such as “no current,” “station short,” or “over current.” 
  

Connection Requirements

• Use two-wire connectors that are DBR/Y or equivalent direct bury splice, made for full submersion and effectively seal moisture out.
• Make all connections per manufacturer’s specifications.
• Verify that no loose, unshielded wiring can touch the soil, water, or another copper conductor causing a leakage of current to the ground or a short circuit across wires.
• Make all splices inside a valve box.
• Mount all connections vertically to eliminate standing water inside the DBR/Y connector.
  

Flow Features in the Irrigation Controller Software

• Learn the flow for each zone
• Use flow data to maximize the number of zones the controller can turn on at once to help shorten your water windows
• In the event of unexpected high or low flow, automatically determine which zone is at fault and alert you without interrupting the rest of the watering cycle
• Protect your site from mainline breaks with configurable high and low flow shutdown settings

Baseline`s Irrigation Flow Sensors and Flow Meters

PFS Series Flow Sensor Features

• Molded Mounting Tee - improved sensor accuracy and low flow performance
