The lobe flowmeter, also known as the Roots flowmeter, is a high-precision instrument mainly used for continuous or intermittent measurement of gas or liquid flow in pipelines. It features high accuracy, good reliability, light weight, long service life, low operating noise, and easy installation and use. The lobe flowmeter can display cumulative flow, instantaneous flow, and single-batch volume on site, and can also output pulse signals,  485 communication, MODBUS protocol, and more.

Product Features

1. Advanced machining and surface treatment processes, wear-free rotation, non-contact sealing, self-cleaning function, and excellent bearing lubrication ensure high measurement accuracy and long-term reliable operation of the flow meter.

2. Extremely wide range: suitable for a broad range of applications.

3. Strong interchangeability: Replacing the flow meter is simple and fast without the need to re-pipe. The dial can be equipped with threaded union pipes and union flanges, with the union pipe height being 75mm (including thread size).

4. High accuracy and long service life:   - Measurement accuracy is Class 1.5 (Class 1.0 for standard meters with special requirements);   - After 15 years of operation under clean gas conditions, the flow meter maintains essentially its original factory accuracy.

5. Very low starting and stopping flow: generally 0.05–1.15 m³/h.

6. Low pressure loss: generally less than 0.5 kPa, minimum 0.08 kPa.

7. Various display instrument options:   · Mechanical counter — features permanent lubrication, long service life, and requires no maintenance.
