  • Page 8: Overview

    <1. OVERVIEW> 1. OVERVIEW The applications of turbidimeters, which have been used for operation or control of filtration plants, are expanding into turbidity detection in chemical processes and in measurement of suspended solid particulates in various types of industrial wastewater. Model TB400G Surface Scattering Light Turbidity Meter is a process turbidimeter employing the principle of measuring surface-scattered light.

  • Page 9: System Configuration

    <1. OVERVIEW> 1.1 System Configuration The TB400G Surface Scattering Light Turbidity Meter comprises a detector, converter and sampling system (which supplies process sample water, zero-calibration water (“zero water”), and cleaning water). This instrument is classified into three types depending on the specifications for the sampling system.

  • Page 10: Tb400G- -A3 (With Automatic Cleaning And Zero Calibration)

    <1. OVERVIEW> 1.1.4 TB400G- -A3 (with automatic cleaning and zero ¨-¨ calibration) This is a system which comprises the TB400G---A1 model with the automatic cleaning and automatic zero calibration functions added (see subsection 2.6.3). The sampling system of this system incorporates solenoid valves at the cleaning water tubing and zero calibration tubing and electric motor-operated valves under the header tank and at the measuring-water tubing.

INSTALLATION, PIPING, AND WIRING 3.1 Installation 3.1.1 Unpacking The Surface Scattering Light Turbidity Meter is shipped only after being packed so as not to be damaged during transportation. When the turbidimeter is delivered, unpack the meter carefully. If the turbidimeter with a sampling system is delivered, unpack them near the location where they are to be installed.

  • Page 55: Installation

    <3. INSTALLATION, PIPING, AND WIRING> 3.1.3 Installation Installation of the Surface Scattering Light Turbidity Meter differs depending on whether the sampling system is provided or not. If the sampling system is provided, secure the entire system with anchor bolts (M12 (12 mm) bolts) to a well-drained “concrete base”. If the sampling system is not provided, mount the detector and converter onto pipes (2-inch pipe) or racks with the special mounting bracket.

Connect the attached ø33 mm X ø25 mm black soft PVC pipe to the Sample inlet. However, if the sample flow exceeds the range of 1.5 to 2 L/min, satisfy the flow condition by providing, for example, a head tank (constant level tank) also used for bubble removal.
