System Layout and Features

The DW- -

monitoring solution for clean water applications including drinking water networks, secondary water

supply and decorative/swimming water applications. The DW-739 series offers highly accurate, real-time

measurement, display and data-logging of Ultra-Low Turbidity utilizing proprietary Pyxis Lab smart sensor

technology in both EPA-180.1 and ISO-7027 compliant formats, coupled with a Pyxis touch screen display

and data logging terminal. The DW-739 series is offered in a convenient and easy to integrate panel

mounted format for rapid installation and simple maintenance.

Figure. 1- DW-739 Series

DW-739 Series Features

research and development sensor technologies to

achieve highly accurate and stable measurement of Turbidity with ultra-low

resolution.

Pyxis LT-739 (EPA) and LT-739B (ISO) ultra-low resolution turbidity sensors

offer a detection light source using warm white LED in 90-degree surface

scatter format in accordance with USEPA 180.1 standards or Infra-Red

860nm in accordance with ISO-7027.1 standards. The turbidity sensors are

mounted in the unique Pyxis FR-100 flow reservoir enabling the highest

resolution possible of 0.001NTU with unmatched stability. The LT-739

and LT-739B offers simple calibration using the Pyxis L-CAL Portable

Turbidity Calibration Kit (uses 500mL Formazin per calibration).

Pyxis FR-100 Single-Sensor flow reservoir provides sample calming for dissipation of air-bubbles and

settling of suspended solids, foam or other impurities commonly observed in drinking water influent.

This unique flow reservoir design results in the highest level of turbidity resolution on the market and

greatly extends the maintenance cycle of the sensor while providing a large buffer capacity to mitigate

pressure fluctuations. The minimum inlet pressure of FR-100 flow reservoir is only 7.5 psi (0.05mpa) making

it highly suitable for the end of pipe networks and secondary supply influent sampling.

Turbidity sensor offers a self-cleaning flat electrode design making them easy to maintain and clean.

Simple sensor removal and replacement. LT-739 sensors is connected to the display/data logger via RS-485

modbus(RTU) allowing for integrated sensor calibration interface and diagnostics within the display screen.

Convenient and simple to install Back-Panel (DW-739 Series) for rapid and easy installation. Truly a

plumb and power to go platform with intense factory setup, testing and sensor calibration prior to

shipment.

7-inch touch screen display/data logger interface with sensor calibration integrated. Display/data logger

offers 2x 4-20mA I/O as well as RS-485 for signal passthrough to any PLC or DCS network. Pyxis CloudLinkTM

4G Gateway version available.

For NSF Certified Applications the DW-739 discharge flow of approximately 200-400mL/minute may be

sent to sanitary drain or returned to the inlet of the pretreatment system.

Installation

5.1. Installation Requirements

Power Supply: 100~240VAC 50/60Hz

Water Supply:Inlet water pressure should be from 7.25 30 psi (0.05-0.2MPa) with an inlet feedwater line

diameter of ¼-inch O.D. Tubing. The DW-739 is provided with an inlet Rotameter and PRV for sample water

inlet flow control and limited pressure regulation. Depending on sample water quality, these items may

be installed on the application needs and user desire. The range of inlet flow for the FR-100 should be

consistently maintained between 200 and 1,800 mL per minute.

Drainage: The FR-100 outlet tube (20mm Tubing) located on the bottom of the FR-100 should be

connected to a discharge drain via gravity flow.

Wall Mount Space: The DW-739 analyzer panel size is roughly 790H x 450W x 235D (mm) in dimension.

Please accommodate sufficient space for mounting.

Wall Mount Weight: Approximately 15kg. Please use appropriate mounting hardware.

3G/4G Network: Make sure your mobile network is a CMCC/CUCC 3G/4G compatible network. Ensure the

signal strength is sufficient in the installation eara.

5.2. Tube connection

Inlet Water: Connect the ¼-inch inlet water tubing to the quick adapter provided. *NOTE* The inlet

flow meter is shipped as a loose item and may be installed as desired by the user. If feedwater water quality is

poor, users may desire to not install this flow meter. Consistent flow of 200-1,800mL is required.

Outlet Line: Connect 20mm tubing to the outlet drain. This is the sample water outlet flow. This

line must be diverted to drain.
