    Portable Total Suspended Solids Meter Model 711 Overview

    The Portable Total Suspended Solids Meter Model 711 is a rugged, waterproof instrument designed for portable sampling. The meter provides reliable operation in wastewater treatment plants, rivers, lakes, and other aqueous systems, and has two measurement modes that readout in either gram per litre or percentage of relative density.
    Calibration values for total suspended solids and interface level are stored in two separate nonvolatile memory locations allowing the user to switch between operational modes without having to recalibrate daily. Typical use requires monthly calibration.

    The Model 711 meter includes a Model 71 reliable sensor, with waterproof and polymer optical grade lenses. It is explicitly designed to meet the rigorous demands of a portable sensor. Additional instruments and cables are sold separately.

    Portable Total Suspended Solids Meter Model 711 Features :

    • Rugged and waterproof housing
    • Two measurements in one instrument:  TSS & Interface Level
    • Microprocessor-based; stored calibration values
    • Automatic ranging
    • Self-diagnostics
    • 9V battery with an automatic turnoff
    • 8-meter or 25-foot waterproof sensor cable with military connector

    Portable Sludge Blanket Level Meter ENV100-P Overview

    The ENV100P portable sludge blanket level meter is designed to offer economic operation where dozens of clarifies exist. User can suit the meter to their specific requirement and field conditions with respective internal data memory and get all measurement data throughout RS232 port after field measurements. Unlike optic measurement device, the user do not need to contact contaminated cable because the ultrasonic sensor is floating on the wastewater.

    Portable Sludge Blanket Level Meter Features

    • Portable in-site Measurement
    • Field-adjustable
    • Measurement Result Outputs Through RS232 Port
    • No Need to Carry and Touch The Contaminated Cable
  • Ultrasonic Sludge Blanket Level Meter (ENV100S)

    Sludge Level Meter ENV100

    The ENV100 Ultrasonic Sludge Blanket Level Meter manufactured by WESS, utilizes enhanced ultrasonic technology to measure the sludge interface level in various types of clarifies, settling tanks and thickeners with superior accuracy and reliability. The instrument continuously provides the user with important information which includes numeric & graphic screens representing the distance to the blanket, an echo profile image to ensure correct configuration during commissioning and saved data analysis. Additional features such as ASF (Abnormal Signal Filter), allows elimination of irregular field noise which can result from moving structures intermittently obscuring the signal. The ENV100 technology additionally incorporates a compressed air cleaning system to maintain the sensor in optimum condition and guarantee maintenance-free measurement. Specially designed mounting kits are also available.

    Sludge Level Meter ENV100 Features

    • Continuous and Real-time Measurement
    • 4 Sensors Measurement with One Controller Enables Economic Operation
    • Maximum 400 Days Data Logging and Monitoring
    • Wireless Option Avoids Cabling Cost
    • Automatic Sensor Cleaning Guarantee Maintenance-free Measurement
    • Built-in Unique Algorithm Eliminates Stationary and Moving Structures
    • Free WESSWARE Software Enables Field Data Analysis and Menu Setup



    Ultrasonic Sludge Density Meter ENV200

    Ultrasonic Sludge Density Meter ENV200 Overview

    The ENV200 is an ultrasonic instrument that measures the density of suspended solids in a liquid. It consists of sensors, a controller, and a junction box.

    ENV200 with PCM(Process Condition Monitoring) algorithm measures not only the size of the received signal which is often measured by conventional ultrasonic density meters but also observes changes in sound velocity and temperatures in the process. As it monitors operational status and water status in the pipe and then decides the validity of each measurement it contributes to increasing stability and reliability of the measurement. The ENV-200 utilizes the EEA (Envelope Energy Average) method that saves reception signal envelop and then calculates its energy, rather than using the reception signal’s amplitude change.

    ENV-200 offers three types of sensors, such as spool-piece, tank-mount, and clamp-on type to accommodate all field demands at installation.

    Sludge Density Meter ENV200 Product Features

    1. Continuous measurement
    2. Process monitoring possible (run, stop, full, empty)
    3. 10,000 points data logging
    4. EEAM(Envelope Energy Average Method)
    5. Various types of sensors
