Débitmètre à engrenage ovale HGLC
Oval gear flow meter is used for the continuous and intermittent flow measurement, it is a kind of positive displacement flow meter, features as follow:
● For fluids with high viscosity and without corrosion
● Easy installation, no requirement to Straight pipe length at upstream / downstream
● High accuracy
● Mechanical counter
● Can be integrated with Pulse-output transmitter or Analog current-output transmitter (on request)
● Communication option for electronic transmitter: RS485 or HART (on request)
Description du produit
Principe
Oval gear meter is generally comprised of a flow transducer and a counter mechanism. The main part of the
transducer is a measuring chamber which consists of a pair of oval wheels and a sealing coupling. The counter
mechanism contains speed reduction gears, adjusting device, counter, and pulse transmitter etc.
In the measuring chamber, a pair of oval wheels and cover plate make a crescent shape cavity which is used as
a measuring unit. The oval wheels are rotated by the pressure difference in the inlet and outlet of the meter and drive
the inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four time the volume
of the cavity, the total revolutions of the oval wheels and the revolution rate will be transferred to the mechanical
counter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller
integration. The attached signal generator converts the rotary axial angular shift to the pulse signal and then transmits
it to the electrical indicator for remote integrated flow and instantaneous flow indication and control.
