Line Meters

Line Meters

Our line meters are all LQS designed components. The line meter is a restrictive device designed to provide system back-pressure, essential to maintain accurate and even product distribution across the air tool or planter. The system operates best at pressures from 0.5 to 6 bar (7 to 87psi).

These are apart of the various Air Tool Terminal Configurations and Planter Terminal configurations.
Follow the LIne Meter Selection Tool below.

Line Meters Selection

To select the most suitable line meter for your application requirements use one of the following formulas to calculate the per outlet flow range.

Use lowest rate/lowest ground speed and highest rate/highest ground speed combinations to calculate minimum and maximum per outlet flow required.

Use the flow rate lookup tables to find a line meter size that delivers the range required. Data provided for water and UAN 32:0:0 at room temperature . Higher viscosity liquids (e.g. 10:34:0) will normally require larger size line meters than water or UAN. Temperature may also influence the line meter size required.
