RDC-CI Chemical Injection Data Logger monitors chemical flow through injection quills and nozzles using positive displacement flow meter to calculate chemical delivery rates. Available for use with variety of chemicals and in operating temperatures ranging from -40 °F to 158 °F (-40 °C to 70 °C). Logger gathers data in 0.0005-gallon increments, and accepts chemical flow rates from 0.5 to 100 gallons per day. Six-month battery life. Detects chemical flow interruptions caused by low tank levels, pump failures, or high-temperature vapor locks. Collected data can be transferred directly to laptop.
