Trimec’s PT series turbine flowmeters for low viscosity liquids

AMS Instrumentation and Calibration presents the PT Turbopulse turbine flowmeter series from Trimec
Flow Products, designed to measure flows of low viscosity liquids such as
fuels, alcohols, solvents, insecticides, milk, chemicals, water and light
hydraulic oils. Available in a range of sizes from 1″ to 4″ (25mm~100mm), the PT
series turbine flowmeters can measure flows from 27 to 4500 litres/minute.

Featuring an axial
rotor and flow guides, the PT series flowmeter needs to be installed in
straight sections of pipe, either horizontally or vertically, so that the flow
is conditioned.

Key features of the
PT series turbine flow meters include Intrinsically Safe (I.S.) approvals; choice
of flanged or threaded versions; robust and compact design requiring very little
space in the piping system; high accuracy and repeatability; low cost of
ownership; wide flow range; certified Exd and I.S. hazardous area versions; quadrature
pulse output option; and ±0.15% custody transfer models available.

Principles of operation

The turbine flowmeters
feature a bladed turbine rotor, which is axially suspended in the pipe. As the
fluid flows through the pipe, it causes the rotor to spin on its axis at a
speed that is proportional to the velocity of the fluid. The movement of each
rotor is sensed by the turbine meter using gears, photoelectric cell or
magnetic pickup installed on the outside of the flow tube or the meter body,
adjacent to the perimeter of the rotor.
