Overview

As a specialist with corrosion protection, Promag W is suitable for every application in the water and wastewater industry as well as for custody transfer. It is the ideal solution for direct underground installation or permanent underwater use. Promag W 400 saves time and costs thanks to the broad functionality of its water- and wastewater-optimized transmitter. In addition, Heartbeat Technology ensures compliance and process safety at all times.

Benefits

  • For direct underground installation or permanent underwater use – certified sensor

  • Secure, reliable long-term operation – robust and completely welded sensor

  • Flexible engineering – space-saving due to sensor without inlet and outlet runs

  • Maintenance-free – no moving parts

  • Safe operation – no need to open the device due to display with touch control, background lighting

  • Time-saving local operation without additional software and hardware – integrated web server

  • Integrated verification – Heartbeat Technology

Application

  • The bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity

  • The specialist in the water and wastewater industry for the most demanding applications

Device properties

  • International drinking water approvals

  • Degree of protection IP68 (Type 6P enclosure)

  • Approved for custody transfer to MI-001/OIML R49

  • Transmitter housing made of durable polycarbonate or aluminium

  • WLAN access

  • Integrated data logger: measured values monitoring
