The Truflo Paddle wheel Flow Meter

The Truflo paddle wheel flow meter is a high rated instrument that provides high precision measurement at a really low cost for liquids of varied applications. The Truflo paddle wheel flow meter is an excellent choice with plastic or metal plastic piping. The Truflo combines a very accurate measurement with a very large LED display, which can be seen from a distance, no flashlight is required. The Truflo Flow Meter also comes equipped with a four-blade paddle…the non-intrusive design equates to virtually no pressure drop.

The Truflo TKS series on its own consist of a settable 1 amp relay output …the relay can be programmed to signal low flow or high flow…perfect for Truflo pump protection or instrument protection.

The  Truflo Flow Sensor also are available in the TKM series, which provides both flow rate and flow total plus a 4-20mA output signal. The TKP series also provides flow rate and Flow Total, plus pulse but does not come with the 4-20mA

Features of the Truflo paddle wheel flow meter:

  • The paddle wheel flow meter, all series is designed with a high accuracy capability of less than ± 1.0% of Full Scale.
  • It features a very selectable unit of flow measurement which actually varies from litre/gallon/kilo-litre.
  • It features a material with the terms, PVC/PP/316SS. This material can resist corrosion whether the pressure is dropped or not.
  • All visuals are indicated at a low cost.
  • There are no mounting kits with the paddle wheel flow meter. All installations are quite easy and straight to the point.
  • The flow range of the paddle wheel flow meter is high (.3m/s-10m/s) (.98ft/s – 32.8 ft. /s)
  • The equipment is easy to program.
  • It has a compact design
  • The flow meter features a big and bright digital display.
  • It features both a vertical and horizontal installations.
  • It has a size range of 1/2” – 4”
  • It has a low pressure drop
  • Output signal (4-20 mA) – (0-5 VDC)-(Pulse)
  • NEMA 4X Enclosure
  • Can work in any corrosive environments
  • Security is password protected
  • True- Union design
  • ½” – 2” (Flanged 3” – 4”)

Application of the Truflo paddle wheel flow meter

The connection method is done by putting together the STD which equals a wire lead 3m in length. Below is a description of the specifications of the Truflo paddle wheel flow meter.
