Mechanical precision for clean fluids.
A turbine rotor spins in proportion to flow velocity, delivering accurate, repeatable volumetric measurement of water, fuels, light oils and solvents. Available with flanged (DN15–DN150) or G-threaded (DN15–DN100) process connections.

±1% of reading under standard conditions with excellent repeatability.
Instantaneous readings with minimal lag.
Stainless steel body for corrosive and high-pressure service.
Modular design allows quick cleaning and part replacement.
Fluid entering the meter spins a precision-bladed rotor mounted axially in the flow path. Rotation speed is directly proportional to fluid velocity, and a magnetic pickup above the rotor converts each blade pass into a clean pulse train — flow rate and total, straight from first principles.
The axial rotor presents little obstruction, so pressure drop stays low across a wide measuring range. In clean or filtered fluids the ATFM-100 holds ±1% of reading with excellent repeatability, and its stainless steel body handles corrosive media, line pressures up to 64 kg/cm² depending on size and connection, and process temperatures to 150°C.
The ATFM-100 is best suited to clean, low-viscosity fluids: water, demineralised water, fuels, light oils, and solvents.
Fuels, light oils and solvents are exactly the clean, low-viscosity media a turbine meter is built for — diesel dispensing, fuel-oil day tanks, and solvent batching all sit inside the rated envelope. Fit a strainer or filter upstream to protect the rotor from suspended solids.
In filtered water and demineralised-water service the meter holds ±1% of reading with excellent repeatability, and the SS304/SS316L body withstands treated-water chemistry. Keep the pipe running full at the meter for stated accuracy.
Each rotor blade pass produces one clean pulse, so the pulse output drives batch controllers, PLCs and totalisers directly — with near-instantaneous response for start/stop dispensing cycles on process skids.
Not suitable for slurries, fibrous media or high-viscosity fluids — for those, see the AEFM-100 electromagnetic flow meter.

Integral meter with flanged process connection across the full DN15–DN150 range — the standard configuration for process piping. Rated 40 kg/cm² on DN15–DN50 and 16 kg/cm² on DN65–DN150.
The same ATFM-100 with a G-threaded process connection on DN15–DN100 — G1 up to G4½ by size — for skids, OEM systems, and utility lines built on threaded pipework. Rated 64 kg/cm² on DN15–DN50 and 16 kg/cm² on DN65–DN100.
The ATFM-100 is supplied with a flanged process connection across the full size range, or with a G-threaded connection on DN15–DN100; connection type is selected at order. Core measurement, material and electronic specifications are common to both versions — pressure rating and dimensions vary with size and process connection. Full dimensional detail is in the datasheet.
