Analog insertion flow meter

Loaded with features and we throw in temperature for free.

The i-captor includes standard features such as highly accurate temperature sensing and is available with both 4-20mA outputs for temperature and flow as well as RS485 Modbus RTU for digital signalling. 

The i-captor is simple, easy to install, very affordable and inherits Weber’s legendary reliability. It does not suffer from accuracy losses due to changes in fluid temperature, has a better than 2% accuracy over range with better than 2% repeatability.

It is the ideal choice for most water monitoring jobs from large chilled water systems with up to 20” pipes to just about any process need.
