A pressure booster pump is very important in every home. It is always used to increase water pressure. Therefore, the water coming to your house will flow smoothly as desired. If you're experiencing low water pressure coming from your water supply or a well, just install a pressure booster pump. It will be worth your consideration. Davey Flow Switch Booster Pumps. Economical, compact, booster systems driven by quiet, efficient, stainless steel pumps. The flow switch control module replaces the conventional pressure switch and provides constant flow without cycling. This feature also provides loss of prime protection.
An example of what flow switches can be used for is given by McDonnell & Miller, suppliers of liquid and air flow switches. Liquid flow switches can be used for air conditioning, hot water space heating systems, pump systems, water cooled equipment, blending or additive systems, liquid transfer systems, fire sprinkler systems, water treatment systems, swimming pool chlorination and industrial laser coolant systems. Air flow switches can be used for clean room filter systems, duct type heating, exhaust ventilating, air supply systems and air treatment systems. Flow Definition. According to the Instrumart website, several different types of flow switches can be found. A vane-operated flow switch utilizes the fluid pushing against a paddle in the liquid flow. When flow drops below pre-set levels, it triggers, according to the site, 'an internal magnetic coupling and mechanical switch actuation lever' which trips the switch.
A variable area flow switch uses several methods to activate the switch, which has an internal piston. Flow comes into a port, creating pressure against a magnetic poppet. When the flow pressure reaches a set level, the switch closes. An ultrasonic (Doppler) flow switch is attached to the outside of the pipe.
It uses ultrasonic sensors to send an ultrasonic signal when a change in flow is detected. A thermal dispersion flow switch is a probe that measures the difference in temperature of the liquid or gas as its passes sensing elements and triggers a signal when a change is detected.
