WORKING PRINCIPLE

User defined sampling timing (1-99s) to acquire sampling pulse signal. Signal is processed to display per second (per minute / per hour) instantaneous flow rate in 4 ~ 20mA signal. When flow rate exceeds pre-set value, relay 1 actions. When total flow reaches pre-set value, relay 2 actions (Relay action time from 1 ~ 99999.9s). Includes a linear flow rate signal output 4 ~ 20mA.

PRODUCT APPLICATION

Food, Feed, Dyeing, Pharmaceutical, Injection Moulding, Various Machinery, Electrical Cabling and wiring, etc.

FEATURES

  • Multi-functional design featuring in Timer, Counter, and
  • Tachometer
  • Accumulation, batch, and dual function
  • OPERATING PRINCIPLE

    Thermal dispersion flow switch is a precise flow sensing device, whose movement principle is heat diffusion. The probe consists of two temperature sensors. One sensor measures the temperature of the fluid when the probe is immersed. The other sensor is heated by a constant power. This creates a temperature difference between two sensors. Temperature difference is an inverse ratio to the flow velocity. The probe and housing are made by stainless steel or engineering plastic. Since the device is without moving parts, therefore there is no wear and tear problem.
