Description

The Saier HW83K employs a precision turbine sensor to measure fluid flow rates. As fluid passes through the sensor chamber, it spins an internal rotor; the rotational speed is converted into a proportional electrical signal, providing accurate flow data. The sensor includes built-in signal conditioning to deliver stable analog or digital output.

Constructed with durable materials, the sensor is rated for working pressures up to 1.20 MPa and features high insulation resistance (>100 MΩ) for safe operation in wet environments. Its low current draw (≤15mA) makes it suitable for battery-powered or low-power embedded systems, including those based on Arduino, Raspberry Pi, or industrial PLCs.

Key Features

  • Precision turbine flow sensor with a measurement range of 0.3 to 10 liters per minute.
  • Broad 4.5–18V DC input voltage compatibility for versatile power supply options.
  • Low-power operation with a maximum input current of ≤15mA.
  • Robust construction rated for fluid pressures ≤1.20 MPa (≈174 psi).
  • High electrical isolation with insulation resistance >100 MΩ and dielectric strength of AC500V/50Hz.
  • Provides both analog (pulse width/frequency) and digital (TTL-level) output signals for flexible interfacing.
  • Compact form factor designed for straightforward installation in plumbing systems and tight equipment spaces.
  • Suitable for monitoring a variety of fluids, including water and compatible gases.

Applications

  • Flow rate monitoring in water dispensers, coffee machines, and vending machines.
  • Hot water circulation and consumption measurement in residential and commercial water heaters.
  • Process liquid flow control in industrial equipment, chemical dosing systems, and agricultural irrigation.
  • Diagnostic fluid monitoring in medical testing devices and laboratory equipment.
  • Smart home automation for leak detection, water usage tracking, and appliance efficiency monitoring.

Frequently Asked Questions

What is the output signal type of the HW83K flow sensor?

The HW83K provides flexible output options. It generates a TTL-level digital pulse signal where the frequency is proportional to the flow rate. It can also be interpreted as an analog signal for systems that read pulse width or frequency directly. The high-level output is ≥4.5V, and the low-level is ≤0.5V, making it compatible with 5V logic microcontrollers like Arduino.

What is the maximum pressure this sensor can handle?

The sensor is rated for a maximum working water pressure of ≤1.20 Megapascals (MPa), which is approximately 174 pounds per square inch (psi). This pressure rating makes it suitable for most residential plumbing systems, appliance water lines, and many light industrial liquid handling applications.

Can this sensor be used with gases or only liquids?

While primarily designed for liquids like water, the manufacturer states the HW83K is also suitable for compatible gases. However, for gas applications, ensure the gas is clean, dry, and non-corrosive to the sensor's internal components. Calibration and accuracy may differ from liquid use, so testing under specific conditions is recommended.

How do I interface this sensor with an Arduino or Raspberry Pi?

Connect the sensor's signal wire to a digital input pin on your microcontroller. The sensor requires a 4.5–18V DC power supply (VCC and GND). On the software side, use a library or code to measure the frequency or pulse interval of the signal. The flow rate can then be calculated using the sensor's specified pulses-per-liter characteristic (K-factor), which is typically provided in the datasheet.
