One flowmeter: 

 AMEF electromagnetic flowmeter sewage electromagnetic flowmeter sensors and the type HPLDEB sewage electromagnetic flowmeter converter supporting is the instrument used to measure the volume of a variety of conductive liquid flow in pipe and channel. 
 The AMEF type flowmeter can be used in municipal water, iron and steel, petroleum, chemical, electrical, industrial, irrigation, water administration and water resources department of the conductive liquid volume flow measurement, especially for the measurement channels, a small river traffic as well as dealing with environmental protection aspects of sewage metering. 

 Second, the sewage flow meter features: 

 Structure is simple, solid and reliable, long life (and is suitable for measuring sea water) 
 No moving parts and resistance components in the measuring tube, no pressure drop, will not produce obstruction 
 Reliable measurement, anti-interference ability 
 Small size, light weight, easy installation, less maintenance 
 Wide measuring range, the measurement is not the impact of changes in fluid temperature, density, pressure, viscosity, conductivity 
 Hole transformation on the old pipeline installation, construction and installation of simple, small quantities 
 Than the general flow meter costs and installation costs are low, especially for medium and large diameter pipe flow measurement 
 The advanced processing technology, solid package, long life, so that the instrument has good measurement accuracy and stability 
 Third, the flowmeter main technical performance indicators: 

 Flow rate measuring range: (0.05-10) m / s 
 Measuring the diameter of the pipe: the DN (32-6000) mm. 
 Instrument accuracy: 1.0 
 Working pressure: ≤ 1.6MPa 
 Medium temperature :0-80 ℃ 
 Power consumption: <15VA 
 Protection: IP68 
 Connection method: flange connection 
 Electrode material: stainless steel containing molybdenum OCr18Ni12Mo2Ti, Hastelloy B, Hastelloy C, titanium Ti, tantalum, etc. 
 Four sewage flow meter installation requirements: 

 1), the installation environment options: 

 Equipment with a strong electromagnetic field, such as large motors, large transformers, large inverter, and so should be kept away. 
 The installation site should have a strong vibration, pipe fixed firmly, changes in ambient temperature (to prevent the solid-liquid two-phase change). 
 The installation environment should be easy to install and maintain. 
 2) Select the installation location: 

 The installation location must ensure that the pipeline is always full of fluid to be measured. 
 Select a small place of the liquid flow pulse should stay away from pumps and valves, elbows, and other local resistance. 
 Measuring two-phase (solid, liquid and gas, liquid) Liquid should be selected that are unlikely to cause phase separation. 
 Measured pipe diameter or circumference is easily measured, and the ellipticity should be smaller. 
 3), length of straight pipe: 

 The sensor is installed pipe upstream side of the straight pipe length should be greater than or equal to 10D downstream side should not be less than the 5D (D is the measured pipe diameter). 
 4), flow control valves and regulating valves: 

 The flow control valve should be installed in the sensor upstream side of the measured pipe, the flow regulator valve should be installed downstream of the sensor side. 
 Flow, usually the flow control valve is fully open state.
