Within the flowmeter industry, pulse output methods to signal flow are common, and we usually find all our clients are also familiar with them. However, across the various use states, we serve, this is not always the case.

The pulse flow meter of Proteus we are providing is created with a square wave pulse output as below. 

Pulse Output

Proteus manufactures five main types of pulse generating flowmeters, each corresponding to the flow from the meter. These include Hall Effect transistors, Reed switches, Namur sensor, and an optical director, initiated by a rotating turbine or gear from our automated meters.

Also, we give a variety of ultrasonic meters, which also provide a pulse flow meter output. The extent of this article is to meet the most generally utilized pulse kinds in everyday technical use.

Hall Effect Sensors

Hall Effect sensor tools give excellent durability and lifespan, as well as being able to work at a high rate. They use solid-state electronics to provide strength to pass through in one spot when activated by a magnetic field passing across them. There are two sorts of Hall Effect sensors. 

Reed Switches

Reed switches are actuated similarly to Hall Effect devices, with a magnet moving across them. As easy physical switching tools, relating and detaching an input or output connection, Reed switches only need two wires and work on much lower power than a Hall Effect sensor. This is helpful where you wish to use battery systems or work in hazardous (ATEX) conditions.         

Optical Sensors

Optical sensors are seldom used on turbine pulse flow meters, as they can give high low flow production for purposes including clear liquids. Titan's infrared optical sensor orders are portable-based, like the Hall Effect NPN sinking devices. With these visual sensors, the output from a light origin is broken by the turning turbine blade, making the output pulsate. As the turbine does not need magnets fixed to begin, the pulse, a much lighter design, can enhance the low flow execution.

Ultrasonic Tools

Ultrasonic flow meters are distinct from other flow tools in that they regulate flow without using any moving parts. They have no turning or renewing factors, which can form pulses directly. The flow is defined by an algorithm providing a number that accurately depicts the flow at that moment. This number is used to incorporate a pulse output (square wave) relying on a parameter often signified as pulses per unit or something related, usually regulated by the user, turned to an NPN or PNP type output as described previously.

In Conclusion

One of the most fundamental problems that pulse flow meter users have is the termination terms of their direction or showing tools. To use the distinct kinds of pulse flow meter output, you must equate it to a system that can understand it, such as a show or a signal processing tool. However, flow meter users usually require to mix directly with their control systems.
