PULSAR MEASUREMENT

This will operate as follows, when the level rises on the upstream side and/or
the level on the downstream side falls, resulting in a differential of 0.5 feet,
(anywhere within the working span), indicating that the screen is blocked,
relay 1 will come on and operate the rake. Once the level on the inflow has
decreased and the differential level falls to 0.1 feet relay 1 will switch off the
rake.
Should the level on the upstream side rise, for any reason, to a level of 8.5
feet, relay 2 will operate to give a high alarm, once the level has fallen back
to 8.0 feet the alarm will go off. A falling level in the downstream side, for
any reason, will operate relay 3 at 1.0 feet giving an alarm for low level, once
the level has risen again to a value of 1.5 feet m relay 3 will reset.
