LS Rotary Piston Flowmeter
Overview
LS rotary piston flow meter is a kind of volumetric flowmeter, also called suspending single rotator flowmeter, which not only has merits of ordinary volumetric flowmeter such as efficient measurement for many kinds of medium, high temperature resistance, high pressure resistance, high precision, reliable operation, etc, but also can measure medium with high viscosity. Its characteristics are simple structure, convenient and fast dismounting. The measuring part can be cleaned without any special tool, just by removing it from the flowmeter. After cleaning, it can be remounted and has the same measuring accuracy as before, without adjusting it could resets. The rotary piston flowmeter has two types, electronic counter and mechanical counter.
Features
1. The piston realizes floating motion and makes little abrasion (free maintenance in ordinary);
2. Small volume, light weight, convenient and quick dismounting.
3. The operating room in piston cavity is big, so tiny particles can be eliminated automatically;
4. Outputs many kinds of signals such as 4-20MA, pulse equivalent, RS485, Hart protocol, and so on.
