LL Roots Flow Meter

Overview of LL-40 Roots FlowMeter

The LL-40 Roots FlowMeter is a volumetric flow measuring instrument, which is used to measure thevolume flow of the fluid in the closed tube. The accumulated traffic isdisplayed in situ, and has long transmission output interface. It is equippedwith the corresponding photoelectric pulse converter and flow integrator, andit can be remotely measured, displayed and controlled.

Characteristic of  LL-40 Roots Flow Meter

1) The accuracy of measurement is high, thebasic error is generally 0.2% to 0.5%, and the special requirement is up to0.1%. The characteristics of flowmeter are generally not influenced by the flowstate, nor by the Reynolds number.

2) It can be used to measure the flow ofhigh viscosity liquid.

3) The measurement range is wide, and thetypical flow range is from 5:1 to 10:1.

4) The word wheel counter accumulates thetotal amount of fluid, without external energy, and is easy to use. Thecumulative traffic of the counter is double displayed, one of which can bereset to zero, which is convenient for users to use in the condition ofcontinuous measurement.

5) No contact between measuring components,no wear, long service life.

6) The large diameter flowmeter adopts theform of double rotor to reduce the noise and vibration of the flowmeter.
