TB820D and TB830D Sampling System Selection Manual
Introduction
This manual describes how to select a sampling system when the analyzer combined with the
“TB820D Right Angle Scattered Light Turbidity Detector” and “TB830D Surface Scattering Light
Turbidity Detector” does not have an assemble stanchion.
If you specify without a sampling device (Su󰀩x code -NN, -A5), you have to select and build
system components such as a head tank, solenoid valve, and manual valve. This document
describes how to select the solenoid valves and head tanks necessary for conguring a sampling
system, as well as piping and wiring diagrams.

2. Installation
The TB820 and TB830D should be installed in a location:
• In a building or a cabinet where no direct sunlight or rainwater can get inside.
Direct sunlight may cause an abnormal rise in the temperature inside the instrument and
discoloration or deterioration of resin parts. Also, removing the cover for maintenance during
rain may damage the electrical parts inside the instrument.
Install the instrument in a building or cabinet away from direct sunlight and rainwater.
• With little vibration
Vibration may result in incomplete connections such as external wiring.
• Where corrosive gases are not present.
Corrosive gas can damage electrical component inside the instrument.
• Where humidity of 0 to 90% RH is maintained (No condensation)
No installing in a place with high humidity.
• With little temperature change, close to normal temperature
The ambient temperature must not exceed the range of -5 to 55°C.
If the temperature of the sample is lower than the ambient temperature, it may cause
condensation.
Take protective measures to prevent a sample and the tap water from freezing, if necessary.
• With adequate maintenance space and easy access for maintenance work.
Secure su󰀩cient maintenance space for maintenance such as replacement, cleaning, and
calibration.
• Where the drain is provided
The sample needs to be drained during cleaning and calibration, so install it in a place
where drainage is possible.
• Near the place where the converter is installed
Consider the length of the connection cable to the converter when installing.

3. Piping

See Section “3.1.1 Head tank and Piping Parts” for head tank types and selection.
nPressurized head tank (/D1)
● Manualcleaning,manualzerocalibration
In a system using an open head tank, air bubbles may form from air dissolved in a sample under
the reduced pressure in piping and enter into the detector, resulting in an incorrect measurement.
For low turbid waters where the e󰀨ect of air bubbles is a concern, install a pressurized head
tank to prevent pressure changes in the piping from the head tank to the detector outlet and thus
prevent air bubbles from occurring in the pipe.
Note: Needle valves are required to adjust the small ow rate by changing the valve opening.

Figure 29 Piping diagram for TB820D /D1 with Automatic cleaning/ With Automatic zero
calibration
(1) Piping of the Sample Line to the Detector
This piping is for introducing a sample into the measurement cell of the detector. Install a
pressurized head tank (for low turbidity), valves and pipes by referring to the diagram in Figure 28
and Figure 29.
1. For the piping from a sampling point to a sample valve, use a hose/tube with su󰀩cient
diameter that provides adequate ow of sample in order to prevent clogging. The hose/tube
also should withstand the sample pressure. The specied sample pressure when using a
pressurized head tank is in the range of 20 to 500 kPa. One example is a rigid PVC tube
with nominal size of 16 (22 mm OD).
2. For the piping between the valve and the pressurized head tank, use a 8 mm OD x 6 mm ID
polyethylene tube and the corresponding tting.
3. To the sample inlet of the detector, attach a 3-way (tee) or appropriate tting corresponding
to the inlet’s connection size (Rc1/2 or 1/2 NPT). This allows switching of the sample ow
and the zero water ow.

TB820D and TB830D Sampling System Selection Manual 19
TI 12E01B30-01EN
4. For the piping between the pressurized head tank and the detector, connect a valve to one
end of the 3-way tee tting and connect a 8 mm OD x 6 mm ID polyethylene tube and the
corresponding tting between the valve and the pressurized head tank.
5. To the tting on the bypass valve (needle valve) at the top of the pressurized head tank,
connect a 8 mm OD x 6 mm ID polyethylene tube.
6. To prevent clogging or stagnation of air bubbles in the pipe line, install the pipes so that no
bends or stagnation occurs.
(2) Piping of the Sample Line from the Detector
This piping is for draining a sample from the measurement cell of the detector during
measurement. As shown in the piping diagram in Figure 28 and Figure 29, connect a needle
valve to the sample outlet of the detector. By adjusting the opening of this valve and the bypass
valve (needle valve) at the top of the pressurized head tank, the pressure change is controlled in
the piping between the head tank and the detector outlet, and thus the generation of air bubbles
is prevented.
1. To the sample outlet of the detector, connect a tting, such as an elbow tting,
corresponding to the connection size (Rc1/2 or 1/2 NPT female) and a needle valve.
2. To the outlet of the needle valve, connect a 8 mm OD x 6 mm ID polyethylene tube using the
corresponding tting to drain the sample to a drain pipe.
3. As shown in Figure 28 and Figure 29, the sample from the detector should be discharged to
the atmosphere at a point higher than the measurement cell of the detector. If not, a siphon
may be created and the measurement cell may not be lled with a sample. In addition, if the
sample inow stops, the sample will be drawn o󰀨 and the measurement cell will be emptied,
which can cause damage to the Pulse Generator for Clean Unit, if used.
(3) Drain Piping
This piping is for draining a sample from the measurement cell of the detector and a head tank
during cleaning, calibration, or other maintenance.
1. The drain of the detector is Rc1/2 (or 1/2 NPT female) thread. Install a tting corresponding
to the thread and connect a hose/tube with su󰀩cient diameter that provides adequate ow
of sample, to route the sample from the detector to a drain pipe. Install the pipe so that no
stagnation occurs.
2. As shown in Figure 28 and Figure 29, install pipe so that the sample can be drained from the
head tank to the drain pipe.
(4) Piping of the Zero Water Line
This piping is for introducing tap water to a zero turbidity lter and then to the detector for zero
calibration or measurement cell cleaning.
1. As shown in Figure 28 and Figure 29, install a tap water valve and a zero water drain valve.
2. Connect a zero water supply valve to one end of the 3-waytee tting attached to the sample
inlet of the detector.
3. Install a tting corresponding to the piping connection of the zero turbidity lter and connect
an hose/tube that can withstand the pressure of tap water, such as a rigid PVC tube. The
ow rate of zero water supply should be in the range of 1 to 3 L/min.
4. For the specications of the zero turbidity lter, see GS 12E01B30-01EN
5. To prevent corrosion of water inside the zero turbidity lter, allow water to ow through
the lter and ow out from the zero water drain valve continuously at a ow rate of
approximately 10 mL/min.

nSimple head tank (/D2)
●Manual cleaning, manual zero calibration
An optional simple head tank with a vent to the atmosphere (option code “/D2”), shown in Figure
38, is available from Yokogawa. The piping diagram of the simple head tank is shown in Figure
30, Figure 31 and Figure 32. The installation of the piping for the simple head tank is described
below.
Note: Needle valves are required to adjust the small ow rate by changing the valve opening.

Needle valve: Keep a very small amount of water owing at all times to prevent contamination of the zero lter and
prevent freezing in winter.
