Non-contact speed sensor model LaserFlow (MCERTS)

- The new ISCO LaserFlow area-velocity flow measurement sensor measures flow in open channels with non-contact technology. To measure the level it uses an ultrasonic sensor and to measure the velocity it uses a Doppler Laser sensor that can perform up to 15 velocity measurements to calculate the flow rate. Suitable for flow measurement in sewers, wastewater and open channels. - The LaserFlow uses a laser beam to measure velocities below the water surface at single or multiple points. - The Isco Laser-Flow flowmeter is the only flowmeter on the market that is MCerts certified with Class 2 certification, without any limitations. Characteristics:

• Non-contact level and speed measurement
• Measurement of the velocity of one or more points below the surface of the liquid.
• Rugged and submersible housing, meets IP68 environmental requirements.
• No deadband for level or speed measurement
• Highly accurate flow rate readings
• Bidirectional speed measurement
