Ultrasonic Level Sensor
The UL7 series sensor based on the ultrasonic technology provide a non-contact method of detecting level measurements. It’s a member of Cross Smart Sensor family which can work independently by 24VDC power supply and output RS485 digital signal with Universal Modbus-RTU protocol. It means that the UL7 sensor can be connected to all devices commonly used (Data logger, PLC, DCS …) and suitable for sensor network applications. It's recommended to work with GDC (General Displayer & Controller) series if a remote monitor is required. UL7 can be calibrated/configured by GDC or by computer with software.
Product Description
This versatility makes them deal for a variety of applications. Ultrasonic sensors are not affected by target surface, color or translucency and they function extremely well in harsh environments. When monitoring liquids, they are not affected by changes in dielectric constant, specific gravity or viscosity.
When connect to GDC terminal, it gives real time reading, analog outputs and relays for field control. It also can be used as open channel flow meter if ordered with the OCF software of GDC which has built-in standard flume measuring formulas, such as: Parshall flume, V flume, Venturi flume and Rectangle flume...
