General information:
The 3 inch Banjo flow meter series are a full-bore, plastic-bodied electromagnetic flow meter designed for flow and usage monitoring applications in 3 inch pipe. 
The polypropylene flow tube offers corrosion resistance to a wide range of chemicals. 
Its light weight and clamp flanges allow it to be easily installed or removed from the pipe for inspection. 
There are multiple configurations.
With no moving parts, the mag meter permits unobstructed flow, minimizing flow disturbances. 
The 3 inch meter series can be used in piping configurations where there is little space between the meter and valve. 
The 3 inch meter series, like other mag meters, are resistant to wear from debris. 
Since there are no bearings or propeller to wear out, downtime and maintenance are kept to a minimum.
Because there are no mechanical parts in the flow stream, the meter tolerates high flows without damage. 
Please note that flow does not automatically turn the meter on.
The hinged, polyethylene cover protects from dust and UV rays,  while permitting easy access to the LCD flow rate and total display.
The electronics housing is made of rugged powder-coated die-cast aluminum. 
Flow rate and total can be displayed in a variety of units, customer-selected and factory-set.
The 3 inch meter series are used for tracking flow rates and total flow in usage monitoring applications. 
These would include wells,industrial wastewater, leach mining discharge, cooling tower deduct metering, turf and landscape applications, and other water reclamation operations. 
When changing the batteries, the 3 inch are designed to retain the internal settings and flow total.
The flow meters are externally powered via a 5-pin connector cable (20 ft/6 m) which also provides pulse output for use with a variety of displays and controls for remote reading, data logging, pulse-to analog conversion, and telemetry applications.
The flow meters are a battery-operated unit for use when pulse output is not required. 
The batteries are user replaceable with an approximate 1-year life under continuous use, or more depending on the duty cycle. 
The flow meters shut off after minutes of inactivity to preserve battery life.

Water use monitoring
Irrigation
Industrial wastewater discharge monitoring
Cooling tower deduct metering

The story behind the Banjo brand.
In 1959 Jack Canine's passion for solving problems began in the garage of his Crawfordsville, Indiana, USA home. 
He soon moved out of his garage and established Terra-Knife, a small supply company that provided fertilizer knives to farmers throughout the United States.
As the agricultural industry continued to grow and the needs for new, innovative products were on the rise, Mr. Canine and his employees met this demand by introducing additional products to the Terra-Knife line, including ball valves and cam lever couplings. 
Shortly after, the company was renamed Terra-Products to better represent its growing product range.
In keeping with Mr. Canine's entrepreneurial spirit, the engineering and manufacturing of new products continued throughout the years, leading to the service of new markets, including many industrial applications. 
Mr. Canine's personal hobby and love for the banjo musical instrument, and the shape of the handle of one of the company's key products, the ball valve, led to the renaming of Terra-Products to Banjo Corporation.
For fifty years, Banjo Corporation has continued to grow and build upon Mr. Canine's vision, commitment to innovation, quality and drive for excellence. 
Today, Banjo Corporation is a leader in the manufacturing of liquid handling products and continues to excel by listening to the customer, focusing on their needs and providing a wide range of high quality products to meet the demands of a varied customer base.
