IR PULSE TRANSMITTER 573

Product catalog summary

Application
The IR Pulse Transmitter 573 is designed for generating high pulse frequencies for electronic processing, remote transmission of flow rate values, pipe leakage monitoring, and control of pumps, valves, and dosing systems.

Features

Sensor replacement without affecting water meter calibration
Interference-free scanning
High pulse resolution

General Specifications
The transmitter works with a reflex impeller to provide a high-resolution pulse frequency proportional to flow rate. It is available in 2-wire (NAMUR DIN 19234) and 3-wire (Open Drain) versions, with an operating temperature range of 0 to 85°C and storage temperature range of -25 to 85°C. It has a protection class of IP 68 and a cable length of 5 meters.

Technical Data

Operating voltage: 8.2 VDC for OPTO N and OPTO VR N; 5-30 VDC for OPTO OD and OPTO VR OD
Current consumption: 0.4 to 3 mA
Output current and voltage: 0 to 50 mA and 0 to 30 VDC
Pulse frequency: 0 to 150 Hz
Signal output: NAMUR or Open Drain with inverse polarity protection

Usability
The transmitter is compatible with various bulk water meters, including models WESAN WS 233, WP 222, WB 234, WPV 228, WPV A 226/216, and WP H 225.

Pulse Rate

DN 50 - DN 125: 1 l/pulse
DN 150 - DN 300: 10 l/pulse
DN 400 - DN 500: 100 l/pulse

Cable Connection
Overvoltage protectors are recommended for long cables. The cable type is LiYY with varying configurations depending on the model.

Dimensions and Installation

Length: 84 mm
Width: 32 mm
Height: 14 mm
Weight: 150 g
