Positive Displacement Flow Meter


Positive Displacement Flow Meter (PD Flowmeter) is a system with freely-moving blades used to measure petroleum products such as fuels, bio-fuels and refined liquid hydrocarbons.

Its simple design with only two pairs of blades and one moving rotor makes it exceptionally robust and allows the user to make significant savings on maintenance costs.


Operating Principle



The product enters the measuring chamber following the direction of the arrow. The rotor and blades assembly (1-2) is set in motion by the pressure of the liquid on blades. A certain amount of liquid (3) is held between 2 blades and then directed to the discharge manifold. The volume of liquid measured at each rotation is therefore equal to 4 times the measured quantity (3). The smooth curves the meter pieces provide a steady, non-fluctuating flow resulting in low head loss. 

Flow Measurement Meter

Positive Displacement (PD) Flow meters
are volumetric flow measurement instruments that measure flow by passing a precise volume of fluid with each revolution. PD flow meters are precision instruments whose internal moving components are hydraulically locked in tandem with the volume of fluid moving through the flow meter.

The result is that the meter can measure intermittent flows, very low flow rates, and liquids of almost any viscosity. The PD meter instantly moves when there is fluid motion, and instantly stops when the fluid motion stops.

    Digital Control Valve


    We offer qualitative range of digital control valves that are designed to perfection and are highly efficient. They are increasingly demanded in the national market owing to their best quality, flawlessness, accuracy, durability and reliability. Manufactured in conformation to the industry standards they are offered at industry leading prices.

    Digital Control Valve is a control valve, used mainly in Automated Loading Terminal for effectively and accurate filling of Tankers & Wagon with precisely measured different type of liquids. This valve is also known as MULTI STAGE-SET STOP VALVE with standard sizes of 2", 3" and 4".


    Valves are available in cast steel body with stainless steel internal parts and imported Buna-N or Viton Diaphragms and 'O' Ring in Flanged End connection to 150# and 300#. The diaphragm used is of best quality, Nylon Reinforced, and imported from USA in Viton or Buna N. Our diaphragms are having high burst pressure, even thickness and excellent flexibility, which gives better control of Valves.

    The innovative Quad Ring Seals are unique in design, assures positive sealing, bubble tight shut-off and zero leakage as per ANSI standards. They are available in all sizes from 2" to 12" However most widely used sizes are 3"(For Tanker Loading) and 4"(For Wagon Loading). It has two solenoid valves, receiving signal from batch controllers to position the valve for low, medium and high flow conditions as programmed. It is used extensively in major oil companies & refineries and abroad.
