SHARKY Solar 775
ULTRASONIC COMPACT ENERGY METER
SHARKY SOLAR 775 is a ultrasonic compact energy meter designed for measuring the energy consumption in solar systems. The measurement principle is static and based on the measurement of the transit time. Ultrasonic technology offers many benefits : no moving parts (prevents wear and tear of the metering components), low pressure loss, large metering dynamics and low start flowrate, insensitiveness to suspended particles...
