Crossflow

Multi-lane, bidirectional tunnel anemometer

The CROSSFLOW provides an open path, cross bore solution for measuring air velocity and direction in a tunnel.

Crossflow

The CROSSFLOW is an open path, cross bore air flow monitor designed to measure air speed and direction in multi-lane and bidirectional tunnels.  The system uses reliable ultrasonic transit time measurements between a pair of transceivers which are mounted and aligned on either side of the tunnel.

The CROSSFLOW is a self-contained, intelligent analyser with industry standard SCADA / PLC interface options including Current Outputs, Digital Relays and RS485 (Modbus RTU). The wall mounted alignment bracketry and quick lock cable plugs ensure the CROSSFLOW is easy to install and commission. With no moving parts the CROSSFLOW is very easy to maintain, there are no regular offline servicing requirements beyond an annual check and clean.
