Flow Switch (Flow Status Sensor)

The Paddle in the River

एका नदीत ठेवलेल्या एका लहान paddle ची कल्पना करा. जेव्हा पाणी flow होते — तेव्हा paddle हलते. जेव्हा पाणी थांबते — तेव्हा paddle पुन्हा rest स्थितीत येते. ती movement एक electrical contact बंद किंवा उघडते.

एक flow switch अगदी याच प्रकारे काम करते — एक साधे, विश्वसनीय device जे BMS ला fluid flow होत आहे की नाही हे सांगते. फक्त दोन states: flowing किंवा not flowing.

BMS मधील Flow Switch Applications:

CHILLED WATER PUMP PROTECTION:
  Flow switch in chilled water pipe
  Chiller must not operate without water flow (coil damage)
  No flow → DI = 0 → BMS stops chiller immediately

CONDENSER WATER FLOW CONFIRMATION:
Flow switch confirms cooling tower water is circulating
No flow → cooling tower fans stopped → chiller protected

AHU COIL FREEZE PROTECTION:
Flow switch in chilled water return
No flow in winter → pipe could freeze
BMS activates heat trace or bypasses valve

Flow Switch vs Flow Sensor:

| Feature | Flow Switch | Flow Sensor |
|---------|------------|-------------|
| Output | ON/OFF (DI) | Continuous (AI) |
| Information | Flowing or not | Exact flow rate |
| Use | Protection, confirmation | Measurement, control, BMS energy |
| Cost | Lower | Higher |

equipment protection आणि simple confirmation साठी flow switch वापरा.
energy management किंवा control साठी तुम्हाला actual flow values आवश्यक असतील तिथे flow sensor (transmitter) वापरा.
