The new UQS7 from Barksdale is claimed to provide new levels of performance and safety in flow monitoring and control of liquids.
The new UQS7 from Barksdale provides new levels of performance and safety in flow monitoring and control of liquids.
Designed for use with water and other water-based liquids it incorporates an ultrasonic sensor to measure the liquid flow.
The flow measurement is converted using the latest onboard modern semiconductor technology and microprocessor to provide a visual indication on an easy to read 12mm LED display.
In addition to the display of the flow the UQS7 provides two programmable switch contacts which may used to monitor low and high flow conditions, together with an anologue 4-20mA output.
This anologue output may be transmitted for remote control and monitoring.
In line installation is quick and easy to G 0.75in or G 1in male connections, and all switch settings may be set using three menu keys.
With the permanent self-diagnostic system any errors are detected and displayed immediately by an alarm signal.
All measuring and switch functions are monitored in millisecond intervals providing fast response of flow changes; the switch settings may be electronically locked to prevent unauthorised adjustments.
The UQS7 is available in three standard flow ranges 10, 25 and 40 litre/min, with wetted parts in brass and viton seals.
It is housed in a compact robust aluminium die cast enclosure with protection to IP65.
The major benefits the UQS7 provides are its compact size of 110 x 110 x 94mm, capability to withstand 25bar pressure, low pressure drop of less than 250mbar, fast response, a clear online display of flow, with two freely adjustable switch points, and an anologue output for remote monitoring and control.
It also conforms to Desina requirements for the German Machine tool industry.
Typical applications would be the monitoring of water flow in cooling systems on equipment generating a great deal of heat.
For example laser welding and robotic welding machines used in the automotive industry, where it is important that any failure in the water flow system is immediately detected to prevent damage to this expensive equipment and processes.
