FES economic electronic flow switch
Product Introduction:
Real time monitoring of liquid flow in the pipeline, providing on off output, and using 6 LEDs to display real-time fluid flow rate status can achieve the following monitoring functions: medium flow, reducing/including flow rate; The medium exists/does not exist; Medium flow/stillness; Monitor the flow rate of fluid in the pipeline, monitor flow interruption, or prevent pump idling It is applied in industries such as petrochemical, power, metalurgy, steel mills, papermaking, food processing, water treatment, battery factories, etc

Conventional flow switches or flow signals are often used for buffle or piston type, releasing on liquid flow power to push the buffle or piston to move, resulting in high water resistance, large flow loss, poor accuracy, and inability to monitor small flow rates The sealing part is sealed with metal corroded pipes, which has poor pressure resistance and are prone to metal fatigue and cracking

Why must we choose a fire flow switch that meets the new regulations
The role of fire flow switches in the field of fire protection is very important, so in terms of selection, it is important to choose safe and related products This is not only because GB50974-2014 standard 11.0.4 has provisions ruling this type of product, but also because if inferior products are selected, it will be very troublesome if problems are present
1. Choosing a fire flow switch that meets the regulations and construction requirements can ensure the correct and safe construction process;
2. The fire flow switch that meets the regulations has advantages such as high reliability, clear instructions, stable signal, and can visibly reduce company expenses during use;
3. The fire protection industry is a high risk and important industry, and there is also great emphasis on the use of equipment It not only requires the fire flow switch to operate stage for a long time, but also requires it to maintain the correct signal flow and start stop pump instructions at critical moments;
4. Compared to fire flow switches, ordinal flow switches have a small adjustable range of setting values, which cannot meet the requirements of fire equipment for setting flow switches The flow switch used in fire protection should also meet complex requirements such as ^ ^ not too sensitive ^ ^ and ^ ^ set value cannot be too small ^ ^, ensuring that the water spraying function is achieved at a specific flow rate;
5. Some flow switch materials on the market are made of brass, with corroded pipe construction and no separation between water and electrical components In this case, if used as a fire water flow switch, it is easy to cause rusting, affecting the correct transmission of water and signals, as well as the opening and closing of the switch The fire flow switch is made of stainless steel material, which is not only completely separated water and electricity, but also avoids rusting and other phenomena
The fire flow switch is very important for the normal operation of fire protection work When choosing such products, it is important to recognize the fire signs and choose the correct fire flow switch
