Product Description

Mechanical/digital output PD flow meter (oil loading /unloading flow meters)

Product Description

The output PD flow meter indicates the measured flow and / or the total amount of fluid in the selected time interval. In simple terms, It is used to measure the fluid flow in closed pipe. The output PD flow meter is commonly used in m3 / hr. and can be divided into flow rate and Total Flow. The instantaneous flow rate is the unit time The amount of excess cross-section or open channel effective cross-section, the flow of material can be gas, liquid, solid;


TWS series output PD flow meter is designed with simple and effective structure composed with body and three rotors. There is no bump among metal so that it is with high accuracy and long working life.

The rotors are propped up by bearings inserted into bearing seat. There is a timing gear at the bottom of each gear bearing and it makes each revolve from calibration regulator and counter.

The excellent micromatic setting (abrading compensation setting) can make plus or minus calibration.

High accuracy and repeatability in wide-range.

Ultra-high accuracy, little maintaining, small abrading and long working life when stable flow.
