Flow measuring system CA400

direct-contactcontrolUSB

Complete system for measuring flow rates in open channels and non-pressurized pipes 2 independent flow measurements Measuring range of sensors 1.5; 6 meters IP68 sensor protection 2 analogue outputs 4 ÷ 20mA 5 totally configurable relays 2 open collector digital outputs 2 analogue inputs 4 ÷ 20mA 2 digital inputs (max 24Vdc 10mA) Datalogger on USB Pen Drive (optional) Description The flow measurement in open channels with the hydraulic projection method is carried out with the use, inside the channel or partially filled pipe, of a hydraulic modeller (BS – venturi / PB channels – palmer bowlus), a probe for the Level measurement (in this case ultrasound (PTU50; PTU51, without contact with the liquid itself) and an associated control unit (VLW90M) VLW90M is suitable for a direct connection of 1 or 2 SGM LEKTRA MODBUS RTU ultrasound sensors. Thanks to this feature, the CA400 system is able to simultaneously perform two independent flow measurements with ultrasonic sensors and different hydraulic modellers for each type of channel. Logger “based on removable PenDrive, allows the total traceability of flow measurements in open channels for which it is very easy to analyze the time profile of the instantaneous flow rates. Installation examples CA400 with Palmer Bowlus Suitable for flow measurement in partially filled pipes of any diameter Employed in the monitoring of sewer networks Ease of installation inside pipes where flow rate measurement is required Resistant to liquids containing acidic and basic solutions
