a. Flow Meter Meod (see Fig 3)
Ensure isolation valves ‘A’ and ‘B’ and bypass valve ‘C’ are fully open. Slowly
close down bypass valve ‘C’ until correct flow rate (See section 5.0 DATA
SHEET on page 61) is shown on e flow meter. Remove handle and lock
off valve ‘C’.
b. Differential Pressure Meod (see Fig 3)
By simply installing two filter pressure indicating gauges, one each on e
inlet and outlet of e heat pump, and a locking type gate bypass valve in e
bypass line, e flow rate rough e heat pump can be accurately determined
by e difference in e readings of e gauges. This pressure drop is
proportional to flow. Flow rate should be set at e maximum differential wi a
clean filter if fitted. This differential pressure will drop as e filter becomes dirty.
Provided e filter is cleaned before e minimum differential is reached (which
would normally be e case wi a well managed system) en no problems
should be encountered.
Setting up e differential
When installation is complete, e procedure for setting e flow rate rough
e heat pump using two gauges is as follows:
1. With the heat pump switched off ensure isolation valves ‘A’, ‘B’ and
bypass valve ‘C’ are fully open.
2. Note the System Pressure on both gauges – they should read the same,
but due to manufacturing tolerances they may be different.
3. Switch on water circulating pump.
For example; wi a water System Pressure of 5mhd e gauge on e inlet
may read 5 and e outlet gauge 5.5 erefore ere is a STATIC ERROR
DIFFERENCE of 0.5mhd.
4. Gradually close the bypass valve ‘C’ until there is a difference in pressure
between the two gauges that is equal to the required pressure drop (See
section 5.0 DATA SHEET on page 61) observing any static error on the
gauges before beginning this process.
5. Lock the bypass valve, or render it tamper proof, when correct setting is
achieved.
6. See section 5.0 DATA SHEET on page 61 for correct water pressure drop.
