The 1" Flow Meter Series are a full-bore, plastic-bodied  electromagnetic 

flow meter designed for flow and usage monitoring applications in 1" 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 magmeter permits unobstructed flow, 

minimizing flow disturbances. The 1" Meter Series can be used in 

piping configurations where there is little space between the meter 

and valve. The 1" Meter Series, like other magmeters, 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 1" 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. In 

the event of DC power loss, or when changing batteries, the flow meter 

will retain internal settings and flow total.
The flow meters are externally powered via a 5-pin connector cable 

(20ft/6m) 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 battery-operated units 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.
