Product Details
KOBOLD Flow Switch KAL-K1315-SPGO from Germany
KAL-K1315-SPGO is a classic model of KOBOLD's KAL-K series thermal flow switch, designed specifically for water-based liquid flow monitoring. It uses the principle of thermal diffusion, has no moving parts, is reliable, and has minimal pressure loss (almost zero), making it suitable for industrial automation systems that require precise monitoring of liquid flow status.
Core advantages:
No moving parts: All stainless steel integrated sensor design, anti vibration, long service life
Intelligent compensation of microprocessor: automatic calibration, adapted to different liquid characteristics (5-minute on-site setting) KOBOLD USA
Extremely low pressure loss: does not affect system flow, especially suitable for low flow rate monitoring
LED traffic trend indicator: 8-segment light bar display, visually understanding the traffic status
Bidirectional flow detection: capable of identifying forward/reverse fluid flow
Multiple output options: 24V DC version provides NPN/PNP output, 110V AC version provides relay output

working principle
The KAL-K series adopts the principle of thermal diffusion measurement and works based on the following mechanism:
The sensor is equipped with two temperature probes: a heating element and a temperature monitoring element
When the liquid flows through the sensor, it takes away the heat from the heating element, causing a temperature difference between the two probes
The larger the flow rate, the more heat it takes away, and the smaller the temperature difference; The smaller the flow rate, the greater the temperature difference
The microprocessor measures the temperature difference in real-time, calculates the corresponding flow rate value, and compares it with the preset value
When the flow reaches the set point, the output signal triggers an alarm or controls the device
Unique advantages: No need for pipeline cutting or installation of additional accessories, direct threaded connection, minimal impact on the system, especially suitable for applications sensitive to pressure loss.
application field
KAL-K1315-SPGO is widely used in industrial scenarios that require precise monitoring of liquid flow:
Cooling system monitoring: Monitoring the cooling water flow of mechanical equipment, hydraulic stations, and compressors to prevent overheating and damage
Lubrication system protection: Flow monitoring of centralized lubrication system for large equipment to ensure sufficient oil supply at each lubrication point
Water treatment industry: Flow control of water treatment equipment to ensure stable treatment effect
Chemical process monitoring: monitoring of reactor feed and circulation pump flow to ensure stable process parameters
-
Food and beverage equipment: Production line liquid (such as milk, juice) flow monitoring, in compliance with hygiene standards
