<mark style="color:red;">\*</mark> <mark style="color:red;"></mark><mark style="color:red;">**IP66 Rating**</mark>\
IP66 stands for Ingress Protection 66. The IP rating is a standard that classifies the degree of protection provided by an electrical enclosure against the intrusion of foreign objects. The format is IPXX, where XX represents two digits: the first digit indicates the level of protection against contact and solid foreign objects (dust protection), and the second digit indicates the level of protection against water ingress. A higher number indicates a higher level of protection. For IP66: the first 6 means complete protection against dust ingress; the second 6 means protection against powerful water jets without harmful effect.

<mark style="color:red;">\*\*</mark> <mark style="color:red;"></mark><mark style="color:red;">**Accuracy Notice**</mark>\
Accuracy is calibrated under controlled conditions using clean water at ambient temperature with CNS UPVC pipes. Actual performance may vary due to fluid properties, pipe conditions, installation, and environmental factors.

<mark style="color:red;">\*\*\*</mark> The device is calibrated with normal temperature water. Fluids with different viscosities may have different results, and may also change the minimum and maximum flow velocity.

<mark style="color:red;">\*\*\*\*</mark> The flow velocity range may be slightly different due to factors such as piping diameter and fluid coefficient.
