Key Features and Specifications (Typical for UT320-00)
Measurement Principle: Transit-time difference ultrasonic flow measurement.

Mounting: Clamp-on (External, non-intrusive). Sensors are mounted externally on the pipe.

Output Signal:

Analog Output: One isolated 4-20 mA DC output, linearly proportional to flow rate.

Digital Communication: HART® protocol (standard) for configuration and diagnostics.

Power Supply: Loop-powered: 12 to 30 V DC (standard for two-wire instruments), typically sourced from the 4-20 mA loop.

Display: Integral LCD display (standard) showing flow rate, totalizer, and diagnostics.

Input (Measured Variable): Liquid flow velocity, which is converted to volumetric flow rate based on entered pipe parameters.

Accuracy: Typically ±1.0% of reading (or ±0.5% depending on sensor type and installation conditions), subject to proper calibration and setup.

Pipe Compatibility: Suitable for a wide range of pipe materials (metal, plastic) and sizes (diameters from approx. 12 mm to 6500 mm, depending on sensor model).

Liquid Compatibility: Works with most homogeneous liquids that can transmit ultrasound, such as water, chemicals, oils, and sewage.

Enclosure Rating: Typically IP67 or NEMA 4X, making it suitable for harsh outdoor and industrial environments.
