1. OVERVIEW
Surface Scattering Light Turbidity Detector, composed of Turbidity Detector TB830D and Liquid
Analyzer FLXA402T, is a next-generation analyzer, developed based on years of experience,
combining the reliable measurement principle with our latest digital sensor technology realizing
high e󰀩ciency in facility operations. The product has successfully extended its life by employing
LED as the light source.
1.1 Measurement system and structure
TB830D is used with FLXA402T Liquid Analyzer for Turbidity and Chlorine. TB830D also can be
used with a sampling system to control the pressure or ow rate of samples.
lTB830D Surface Scattering Light Turbidity Detector
TB830D measures turbidity. The Detection unit consists of the following three parts.
● Flow cell: A sample ows through it. A light beam is emitted from the light source
onto the sample solution.
● Detection unit: An optical system incorporating a Light source, Receiver, and lenses.
Desiccant equipped helps the dryness inside.
● Smart unit: Memory of parameters, the control unit
l FLXA402T Liquid Analyzer for Turbidity and Chlorine (converter)
Displays/Outputs measurement or status of connected detectors or controls detectors.
Refer to IM 12A01G01-03EN for the setup of the display, input/output, or communication.
l Sampling System
The Head tank enables the pressure of a sample and the ow rate to stabilize. The Head tank
also reduces the e󰀨ect of air bubbles.
For Automatic cleaning/Automatic zero calibration, a Relay box and/or solenoid valve is mounted.

If you need to provide conduit work with cables, specify the conduit adapter by Option code.
Conduit adapters and dedicated cable glands, which are used in place of the standard cable
gland for cable entry holes, are supplied with the product.
You can specify the conduit adapter by Option code for both TB830D and FLXA402T, however,
be aware of the following.
• When FLXA402T Digital communication “-E” (Modbus TCP/IP) is selected
If you attach a conduit adapter on the Modbus TCP/IP cable entry, you need an Ethernet dedicated conduit adapter. Be sure to
specify FLXA402T “/C□6”.

1.6 Measurement principle
TB830D is a surface scattering turbidity detector.
It is comprised of a Flow cell, Detection unit, and Smart unit.
The sample owing in from the lower side of the Flow cell overows at the upper part of the Flow cell.
At the same time, the LED light source of the sealed Detection unit irradiates the light beam to the
sample surface through the plural lenses.
The irradiated light is divided into transmitted light, reected light, and scattered light at the liquid
surface.
Transmitted and reected light disappears in a dark room equivalent to a blackbody.
The intensity of the scattered light (L) is proportional to the turbidity as shown in the following
equation.
Ls = K · Q · S
Where:
K: Constant due to turbidity
Q: LED light intensity
S: Turbidity
The scattered light is converged by the lens inside the Detection unit to be detected by a light-
receiving element (silicon photodiode).
The Detection unit incorporates a comparator to detect LED light intensity.
The lens of the Detection unit has a built-in transparent heater to prevent the e󰀨ect of condensation.
The Smart unit controls the light source drive circuit based on the signal from the comparator so
that LED light intensity (Q) keeps constant.
Turbidity is calculated by performing arithmetic on the basis of the turbidity signal from the light-
receiving element (silicon photodiode).
The Smart unit also functions as a power supply for measurement, memory storage of parameters
such as calibration parameters, and a communication device between the detector and the converter.

2. INSTALLATION, PIPING, AND WIRING
The “TB830D Surface Scattering Turbidity Detector” is shipped after being fully packaged so that
it will not be damaged during transportation. Unpack carefully near the installation location.
The TB830D may also be shipped embedded in a Sampling system.
n Installation Location
The 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 (without sampling system)
Consider the length of the connection cable to the converter when installing.

n Installation
See GS12E04B40-01EN for the dimensions of detectors and mounting brackets. For the
converter, see the user’s manual of FLXA402T IM 12A01G01-02EN.
It the sampling system is not provided, it can be wall mounted or pipe mounted.
For wall mounting (Option: / R), mount with 4 M5 screws (not included).
For pipe mounting (Option code: / U), mounting bracket for replacement is available.
See GS 12E04B40-01EN for details.
If the sampling device is provided, x it to a well-drained concrete foundation with anchor bolts
(M12).

2.1 Piping
2.1.1 For TB830D-□-□-NN, -A5 (without sampling system)
(1) Sample piping
If the ow rate of the sample is 1.5 to 2 L/min, the sample can be introduced to the detector
as is. Connect the supplied ø33 × ø25 mm black soft vinyl chloride tube to the sample inlet.
However, if the ow rate of the sample exceeds the range of 1.5 to 2 L/min, install a head
tank (constant water level tank) that also serves as a defoaming tank to meet ow rate
requirements. Connect the ø33 × ø25 mm black soft vinyl chloride tube to the pipe between
the head tank and detector.
(2) Drain piping
Connect the supplied ø33 × ø25 mm black soft vinyl chloride tube to the drain port of the
detector.
At this time, install piping with care to prevent accumulation in the tube. Accumulated water
in the drainage pipes may cause problems such as overow from the detector.
(3) Cleaning water piping
The cleaning water inlet of the detector is sealed with a blind plug.
(Note) When measuring low turbidity (200 NTU or less), prepare a sampling system capable of supplying zero water (ltered tap
water with a zero turbidity lter).

(1) Sample piping
This piping is used to feed the sample to the detector.
The pressure condition of the sample is 20 to 500 kPa, and the ow rate is 2 to 10 L/min .
The pipe joints are rigid PVC pipes with a nominal diameter VP16 (O.D. ø22mm). Before
piping, install any ttings that match the pipe diameter, such as unions or anges.

<2. INSTALLATION, PIPING, AND WIRING>2-5
IM 12B01B30-02EN 1st Edition : Mar. 08, 2023-00
(2) Tap-water piping
This is a piping for supplying detector with cleaning water and zero water. Use tap water or
other water with a turbidity of 2 NTU or less. The pressure of the water to be used is 100 to
500 kPa . The pipe joints are rigid PVC pipes with a nominal diameter VP16 (O.D. ø22mm).
Before piping, install any ttings that conform to the pipe diameter in the same way as the
sample piping.
You should install a check valve before the tap water pipe to prevent backow.
(3) Drain piping
This piping is for discharging the sample and tap water supplied to detector into drains, or
the like. The pipe joints are rigid PVC pipes with a nominal diameter of VP40.
Connect a rigid PVC pipe with a VP40 or higher capacity, and connect the pipe so that
sediment does not accumulate or drain stagnations in the pipe.
