Ultrasonic Flowmeter TFM5100-NG

The Transit Time Flow Meter TFM5100-NG measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream into a pipe.

This flow meter is mostly used to measure the flow rate of homogeneous fluids, also with a quite high percentage of suspended solids.

Product Description

The Transit Time Flow Meter TFM5100-NG measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream into a pipe.

This flow meter is mostly used to measure the flow rate of homogeneous fluids, also with a quite high percentage of suspended solids.

High Accuracy measuring: Linearity: better than 0.5%, Repeatability: better than 0.2%, Accuracy: better than ±0.5% (for speed >0.5 mt/sec)

Wide measuring range: Several types of transducer to be selected, measuring pipe size from DN15mm to DN6000mm with four different types of sensors.
