BBZ 4-20mA Current Signal Output RS485 Conductivity Fluid Flowmeter/ Suitable for Conductivity Fluid
Brief Introduction:
BBZ 4-20mA current signal output RS485 conductivity fluid flowmeter can output 4~20mA current signal for recording, regulating and control while meet the need of local display, and now widely used in chemical industry, environmental protection, metallurgy, pharmaceutical, paper, water supply and drainage technology and administration department.
Features:
Good accuracy and stability
Tyas well as 1-2000HZ frequency output
Digital communication output: RS485
Simple structure, solid, no moving parts, long-term life
Reliable measurement, anti-interference ability
Small size, light weight, easy installation, small maintenance
Wide measurement range, the accuracy not affected by temperature, density, pressure, viscosity, conductivity and other changes, the pressure loss is zero
Can be installed and disassembled in the case of continuous flow, convenient for users.
Lower manufacturing costs and installation costs than general electromagnetic flowmeter, especially for the flow measurement with medium and large diameter pipeline
Advanced processing technology, solid package, shock-resistant
