Installation Instructions
Step 1. Snip out the marked side tabs of the lid
Step 2. Remove the foil covering the induction sensor and the plastic O-ring if still present.
Step 3. Screw the PR7 down firmly on the lid using the fine thread screws provided, ensuring the induction sensor is over the metal spindle on the meter.
How to Calculate Pulse Rate
Step 1: Check pulse factor on the meter.
In the figure, this meter has a factor of 1 (PR7P:1)
Step 2: Check the k-factor on the sensor. This is the second number after the K.
K2 = 100. This output will compensate for reverse flow
Litres per pulse = (meter K factor) x (PR7 K2 factor)
In the above example (1 x 100) = 100L/pulse
