GPI Flow Meters Used: G2P05N09GMA

Problem:

Opening the pipe to measure sample flow rate could expose technicians to toxic levels of ozone. Leaving valves wide open wastes large volumes of water. If the flowrate is to low or too high analyzer readings are not accurate.

Flow Meter Application:

At the end of the ozone chambers, there are instruments for measuring residual levels of ozone. These ozone analyzers require 1-5 GPM. The sample line runs to a closed waste line, in case there is a high level of ozone. Safety to technicians is a concern when working with ozone. Leaving valves wide open wastes too much water. Flowrate cannot be too low or too high and still expect accuracy in the analyzer reader. Rotameters had been used but failed due to turbidity levels and the float would stick.

Solution:

G Series Meters added to the individual lines send a signal (4-20 mA) back to the PLC. This signal at the PLC allows operators to monitor usage throughout the process.

Advantages of Using GPI Flow Meters:

• Cost Savings
• Safety
• Compact Size
• Accuracy
• Easy to Install
