Teejet 1 1/2" 9-90 GPM Rapid Check Flow Meter, insert only
TeeJet Rapid Check Flow Meter; Insert Only
TeeJet Flow Meter, Insert Only is available in 3 different sizes shown below.
Rapid check flow meters are designed to allow their measurable flow range to be quickly and easily changed by switching inter-changeable inserts. This allows the flow meter to operate over wider flow ranges than standard flow meters.
The flow meter should be calibrated after:
- Installation
- Changing Inserts
- Changing to a different chemical
- Changing plumbing
See your operators manual for calibration instructions. Record the "fine tuned" calibration number for each insert used so that the flow meter will not have to be re-calibrated each time any change is made.
The flow meter/insert combinations should have the following initial calibration numbers: (Click image for larger view)
