Example Applications

INDUSTRIAL

• Safety showers & eye washing equipment – ensures adequate flow to all shower stations. Controlled flow = safe flow to eyes.
• Dust suppression – ensures consistent flow from all spray nozzles.
• Fire fighting 
  • guarantees availability of adequate flow to all hydrants in the event that they all require water at the same time.
  • controlled max flow ensures safe and correct flow from each nozzle.
  • for use in conjunction with smaller nozzle for correct dosing of foaming agent.
• Industrial linen washing machines – controlled flow maintains the mains pressure.
• Distilleries and cooling equipment – minimises waste, by controlling condenser cooling water flow.
• Power station – demineralisation water treatment equipment.
• Plant wash-down hoses
• Chemical dosing flow control

 
WATER AUTHORITIES

• Limiting maximum flow, helps ensure maximum consistent mains pressure will be maintained during peak demand. 
• This can help ensure the last property on the line gets its fair share, and may also prevent the costly exercise of needing to increase the mains pipe size to cope with an increased population. 
• Significantly extended water meter life is obtained when maximum flow is kept within meters design parameters. 
• May facilitate an economical means of distributing water to vast areas of semi-rural, sparsely populated country.  A very small and inexpensive water main, perhaps as small as 50 mm, and hundreds of kilometers long may be used if flow is limited to a fraction of a litre per minute per customer. Consumers fill their own tanks for a practical supply. 

COMMERCIAL

• Ensure that every shower, on every floor of a hotel has an adequate and constant flow. 

 
IRRIGATION AND FARMING

• Centrifugal pump protection – Maric flow controllers can prevent cavitation or thrust bearing damage caused from excessive flow rate.
• Preventing electric motor overload – limiting pump output also limits power draw and potential overload tripping.
• Preventing nuisance low-pressure motor tripping - often caused by too high a demand from too many irrigation blocks open at the one time. It can be a long walk or drive to re-start pumps!
• Fertiliser dosing for irrigation
• Vitamin dosing for stock – dosing equipment.
• Prevent pumps from tripping on overload
• Equitable distribution over vast distances (cap and pipe the bore schemes) – provides an economical means of distributing water to numerous properties over vast distances. Limiting flow to a known maximum flow rate will ensure mains pressure is maintained and the last property will receive their allocation.
• Irrigation Water Treatment – Backwash flow rate control
• Sprinkler control – over-spraying wastes water and under-spraying wastes time (ensures consistent output irrespective of sprinkler elevation or available pressure.)
• Tank / water trough fill rate control – Limiting flow to known maximum flow rate, will ensure adequate line pressure to the end of the water main.
