Features
- Low start-up flow rate.
- Volumetric rotary piston principle of measurement.
- LXHY-15~20 is no location limitation for installation. Accuracy is not to be affected wherever installed at a horizontal, vertical or inclined pipeline.Register is sealed with a special liquid to keep a clear reading in long term service.
- Mechanism use of high-quality material to ensure a stable characteristic.*Accurate measurement with conformity to lS0 4064 Class C On request, the series can be equipped with a kind of remote transmission device.
