SI-500C Integrated Flow and Temperature Sensor can monitor the flow and temperature of liquids in the pipeline in real time. Dual functions, optional 4-20mA output!
Provides flow alarm switch output, temperature 4-20mA signal or switch output. And uses LED digital display of current temperature and flow rate. And can set alarm contact output through the header. Realize the integrated monitoring function of temperature and flow in the pipeline.
Features
- Minimal pressure loss.
- Can effectively prevent winding of winding objects in the medium.
- Fully waterproof housing design, unique waterproof adjustment knob.
- Suitable for a wide range of pipe diameters, arbitrarily adjust the set point.
- Optional high-pressure type, with a maximum pressure resistance of 600Bar;
- Optional anti-corrosion type.
- The indicator light directly displays the flow change.

How to select a flow switch?
First, you must understand what type of flow switch you are buying. Different types have different materials and uses, so the prices will not be the same.
For example, the price of an ordinary thermal flow switch and a relatively high-demand explosion-proof flow switch can be twice or even higher. If it involves corrosion resistance and other requirements, the price may be higher.
Secondly, the operating conditions and product technical recommendations.
Before purchasing, you need to confirm the following.
- What is the power supply voltage, DC or AC or 24V or 220V;
- How many VA is the power consumption, it depends on your needs;
- Output mode, there are normally open and normally closed options;
- Is it required to be PNP, NPN or relay;
- Contact capacity, generally the flow switch can display whether the flow reaches the set value by setting the flow.
- Whether the contact medium needs corrosion protection.
- Whether the use environment requires explosion-proof and dustproof.
Finally, you must communicate clearly with our sales engineers before purchasing. Confirm the on-site working conditions, usage conditions, and functions to be achieved. Otherwise, if you cannot use it on site, it will not only bring inconvenience and trouble to yourself, but also delay the construction period and cause unnecessary losses.
SI-500C Integrated Flow and Temperature Sensor is a Dual Function instrument. It monitors and controls temperature and flow at the same time, saving our cost of pipeline fluid management and improving efficiency.
Sino-Inst’s flow sensors and flow switches are widely used in hydropower plants, petrochemicals, electricity, metallurgy, steel mills, papermaking, food processing, water treatment, battery plants and other industries.
