E+H L400 电磁流量计测量原理Electromagnetic
Product headlineThe flowmeter with integrated web server and a weight‐optimized sensor. Fully suitable for standard applications in the water and wastewater industry.
Sensor featuresReduced installation costs – flexible mounting by one‐of‐a‐kind lap-joint flange concept (DN < 350/14"). Energy‐saving flow measurement – no pressure loss due to cross‐section constriction. Maintenance‐free – no moving parts. Up to 30 % less sensor weight. Nominal diameter: DN 25 to 2400 (2 to 90").
Transmitter featuresSafe operation – no need to open the device due to display with touch control, background lighting. Time‐saving local operation without additional software and hardware – integrated web server. Integrated verification – Heartbeat Technology?. Transmitter housing made of durable polycarbonate or aluminium. Same housing concept for compact/remote version.
