Overview:
EFOUMFM-325 is a wall-mount, clamp-on type ultrasonic flow meter which uses transfer time technology. Designed using FPGA chip and low-voltage broadband pulse transmission. Both Clamp on type sensors and Insertion type sensors are available. EFOUMFM-325 has a 320 x 480 backlit Color TFT with 10-line menu display and also the clear, user-friendly menu selections make flow meter simpler and more convenient to use. Daily, monthly and yearly totalized flow. Parallel operation of positive, negative and netflow totalizes with scale factor (span) and BTU Capacity. While the output of totalize pulse and frequency output are transmitted via relay and open collector. It could add the RTD model and temperature sensor become an energy meter to monitor the energy use, helping to save the energy. It is equipped with an all-metal casing, providing high protection. It has excellent conductivity and heat conductivity and boasts outstanding durability and impact resistance.
Application:
EFOUMFM-325 ultrasonic flowmeter is widely applicable in HVAC, water treatment, irrigation.
