3 Safety 4 Items required
4.1 Single-stream wet-sections (hydrazine / sodium)
1 x flowmeter upgrade kit, part number AW500 040
4.2 Multi-stream wet-sections (sodium)
3 x flowmeter upgrade kits, part number AW500 041
Warning.
These procedures must be carried out by a trained
technician.
CHEMICAL
Ensure personal protective equipment (PPE) such as
gloves and eye protection are worn during any
maintenance.
Observe all health and safety procedures for handling
chemicals.
To familiarize yourself with handling precautions, dangers
and emergency procedures, always review the Material
Safety Data Sheets prior to handling containers,
reservoirs and delivery systems that contain chemical
reagents and standards.
Take care if cleaning any spillages and observe all relevant
safety instructions. Wipe up any spillages using clean
water.
Perform general cleaning of the wet-section using a damp
cloth only – mild detergent can be used as a cleaning aid.
Do not use Acetone or any organic solvents.
ELECTRICAL
Isolate all high voltage supplies to the transmitter before
performing bottle / label replacement procedures.
The wet-section is vulnerable to electrostatic damage.
Wear an anti-static strap or dismantle the wet-section on
an anti-static workbench.
Ensure all electrical connections are kept dry at all times.
GENERAL
Shut off the external sample supply to the wet-section
before performing replacement procedures. When a
procedure is complete, restore power to the transmitter
and sample to the wet-section at the correct flow rate. If
necessary, calibrate the wet-section – refer to the
wet-section Operating Instructions (sodium
OI/ASO550-EN or hydrazine OI/AHM550-EN) for
calibration instructions.
Dispose of the old components in accordance with the
guidelines contained in the Operating instructions
(sodium OI/ASO550-EN or hydrazine OI/AHM550-EN).

5 Flowmeter upgrade procedure
Referring to Fig. 4.1:
1. Disconnect external sample tubing Afrom each inlet hose
connector Bon underside of the wet-section and allow to
drain.
2. Disconnect sample inlet tubes Cfrom the barbed
connectors Don the top of each inlet assembly Eand
discard stream 2 and stream 3 tubing.
3. Loosen locknuts Fon the underside of each inlet assembly
Eand pull each inlet assembly adaptor out from the top side
of the wet-section.
4. Fit new adaptors G(1 supplied with each kit) as follows:
– fit the stream 1 adaptor (single- and multi-stream) into the
inlet hole below locknut Hand secure in position using
locknut Hon the top face of the wet-section base.
– for stream 2 (sodium multi-stream only), punch- or cut-out
the knock-out below locknut I, fit the stream 2 adaptor
into the inlet hole and secure in position using locknut I
on the top face of the wet-section base.
– for stream 3 (sodium multi-stream only), punch- or cut-out
the knock-out below locknut J, fit the stream 3 adaptor
into the inlet hole and secure in position using locknut J
on the top face of the wet-section base.
5. Re-connect stream 1 sample inlet tube Cto the barbed
connector on the new stream 1 adaptor.
6. Push the stream 1 flowmeter Kinto the QD coupling L
ensuring the flow arrow on the flowmeter body is facing into
the wet-section.
Hydrazine and sodium single-stream wet-sections only –
proceed to step 11.
7. Connect a 190 mm (7.5 in.) length of new sample inlet tube
Mbetween the stream 2 (S2) manifold inlet Nand the
barbed connector on the stream 2 adaptor.
8. Push the stream 2 flowmeter into the stream 2 QD coupling
ensuring the flow arrow on the flowmeter body is facing into
the wet-section.
9. Connect a 245 mm (9.6 in.) length of new sample inlet tube
Obetween the stream 3 (S3) manifold inlet Pand the
barbed connector on the stream 3 adaptor.
10. Push the stream 3 flowmeter into the stream 3 QD coupling
ensuring the flow arrow on the flowmeter body is facing into
the wet-section.
11. Remove and retain the 4 PCB cover fixing screws and
washers Qand remove PCB cover R.
12. Remove the upper cable gland blanking plug from the top
right-hand side of the PCB housing taking care not to lose the
locking nut on the inside.
13. Fit a new cable gland Sin place of the blanking plug
removed at step 12.
14. Punch- or cut-out the hole Tin the base of the wet-section
and feed each flowmeter cable (supplied) through and up to
the PCB housing.
15. Feed the each cable through cable gland Sand connect the
flowmeter wires to the PCB terminal block numbers shown in
Table 4.1:
*Stream 1 – sodium and hydrazine single-stream wet-sections
**Streams 2 / 3 used with stream 1 for sodium multi-stream
wet-sections
16. Tighten cable gland Sto seal the cable(s) into the gland.
17. Connect each cable to the correct flowmeter cable connector
(stream 1 cable connector to flowmeter S1, stream 2 cable
connector to flowmeter S2, stream 3 cable connector to
flowmeter S3).
18. Change the (external) sample lines or adapt to 3/8in. ID flexible
tubing and fit onto the correct inlet of each flowmeter.
If necessary, secure using a hose clip or similar.
19. Ensure the O-ring Ubetween the PCB housing and cover is
located correctly in the PCB housing groove and refit the PCB
terminal cover Rto the PCB housing using the 4 PCB cover
fixing screws and washers Q.
20. Restore power to the transmitter and refer to the wet-section
Operating instructions to configure the software to enable the
flowmeter(s):
– OI/ASO550-EN Sodium
– OI/AHM550-EN Hydrazine
21. Re-introduce sample to the wet-section and check that the
flowrate is displayed on the transmitter.
Note. If upgrading a single-stream wet-section, fit
the new stream adaptor in the 2nd inlet hole from the
right in the base. The hole must be punched or cut
out of the knock-out.
Caution. Inlet tubing must be the specified length and
type to ensure correct operation.
