Instrumentasi Air

Jika kita ingin membuat sistem kendali air, maka ada beberapa komponen yang diperlukan (tergantung sistem yang dibuat):

  • Sensor ketinggian air
  • Sensor aliran air / flowmeter
  • Pompa air
  • Katup / valve

Untuk sensor ketinggian on-off mudah didapat di toko bahan bangunan. Jika kita ingin ketinggian air secara detail agak sulit, dan harga sensornya agak mahal.

Pompa air mudah juga didapat di toko bahan bangunan.

Katup/valve agak sulit didapat, mesti dicari di toko khusus industri, misal di daerah Cikapundung di kota Bandung

Sensor aliran air juga lumayan susah didapat.

Berikut ini beberapa komponen instrumentasi air yang ada dijual secara online:

Flowmeter  YF-S203 1/2″ Water Heater Flow Transducer Meter – Black



SpecificationMinimum voltage: DC4.5 5V~24V; Maximum current: 15 mA (DC 5V) ; Working voltage: DC 5~18 V; Load capacity: 10 mA(DC 5V); Temperature range: 80’C; Humidity: 35%~90%RH(no frosting condition); Water gage: below 1.75Mpa; Storage temperature: -25~+ 80’C; Storage humidity: 25%~95%RH; Frequency: F=7.5 x Q(L/Min); Error: ±2%; 1L water for 450 output pulse; Flow range: 1-30L/min; Minimum/maximum voltage: 4.5V/24V.
FeaturesWater flow sensor is mainly composed of plastic body, the flow of rotor components and hall sensor. It is placed in the water heater inlet, used to detect water flow, when the water through the water flow rotor components, magnetic rotor rotation and speed changes with the flow, hall sensor output pulse signal, the corresponding feedback to the controller, the controller to judge the size of the water flow, adjust and control.
ApplicationSuitable for water heater, imprinter, SHXRO and other flow metering device.
