Flow-thru Vessels

D 702/N – Oxygen Flow-Thru Measurement

In principle the flow-thru vessel D 702/N for continuous oxygen measurement can be fitted with all TriOxmatic® sensors of the 690/70X (IQ) series. However, it is primarily intended for oxygen measurements in the ppb range (TriOxmatic® 702 IQ), e.g. boiler feed water. In this application the flow-thru vessel is usually installed in the bypass of a water circulation system. Please select an adapter from the table.

VIS Flow-thru – UV/VIS sensors in flow-thru measurement

Flow-thru cell for UV/VIS sensors NitraVis®/CarboVis® and NiCaVis® 700 IQ (TS). The sensor can be cleaned automatically in mounted state by means of compressed air.

Retractable Armatures

  • For pressurized applications up to 10 bar (overpressure)
  • Insertion and removal of sensor during ongoing operation
  • With compressed-air cleaning (optional)

Online measurements, of suspendend solids in particular, are increasingly performed directly in pipework or pressurized containers. Retractable armatures are used in order to enable assembly and removal of sensors during ongoing operation without interrupting the process. Depending on working pressure, these require suitable assembly aids in order to re-insert the sensor against the working pressure.
Apart from the two retractable armatures (for various pressure ranges) there are two different welding sockets (steel or stainless steel) and different matching adapters for mounting of the various online sensors with a shaft diameter of 40 mm (1.57 in.) available.

Cleaning System

Option 2:

Compressed-air supply is not provided at the plant
You require the following components

For cleaning, compressed air is blown at the sensor element (from external source) freeing it from pollutants. The compressed air from the cleaning air box or installation to the sensor is switched on or off electronically by an activated control valve or relay. The control is regulated by a timer via the IQ SENSOR NET or via a relay of the measuring system.

Cleaning Air Box

  • Oil-free compressed-air
  • Most easy installation
  • Decentralized weatherproof compressed-air supply on site

The cleaning air box is a air-pressure compressor supplying the cleaning air to the various sensors.
Compared with the former systems with the cleaning head valve (CHV) the cleaning air box does not require any special valve installation as well as no compressed-air supply on site.
The cleaning air box can be controlled by any WTW supplied converter via a relay (exception: MIQ/VIS).
The great advantage of this cleaning air box compared to any former systems with CHV (cleaning had valve): No compressed-air system is required on site. The cleaning air box is delivered in two models 115 VAC (480 017) and 230 VAC (480 019).
Thanks to the installation of the membrane compressor and the pre-switched filters, the cleaning air box provided oil and dust-free compressed-air, which guarantees keeping the sensor clean.
