Litre Meter developed the Pelton wheel principle as the best to achieve accurate measurements of low flows.
A single turbine ring size is common to all Litre Meter flowmeters. The turbine rotor is based on a highly efficient 'Pelton Wheel' design. It is available in various chemically resistant materials such as PFA (Teflon)and PVDF. The rotor ferrites are sealed to make them non-wetted parts. Sapphire bearings are offered for maximum chemical resistance as standard. These provide a very low friction mechanically-robust bearing with long life characteristics.
The rotation of the rotor is sensed by an electronic system using the interaction of ferrites in the rotor tips with a pickup coil. No drag is imposed on the rotor which assists in the measurement of extremely low flows. This, coupled with the efficient Pelton Wheel design and low friction bearings gives the meter major advantages. The complete turbine ring assembly can be easily removed with the meter remaining in line if cleaning is required.

FTB790 Series turbine meters with microprocessor-based electronics offer a durable, compact, high precision fluid measurement device, with total and rate indication. Information is clearly displayed on a large 6-digit liquid crystal display with two-point floating decimal for totals from .01 to 999,999. All operations are easily performed with two buttons for simplicity. The basic unit and display are powered by two lithium batteries, providing up to 4000 hours of actual use. Automatic “on” and “off” save battery life. Manual “on” allows view of the display on demand. Cumulative total, batch total and rate of flow are standard. A fifteen-point field calibration curve can be stored in memory. The turbine meter can also be ordered without display electronics. A special pulse output model (FLSC790-ND-P) must be ordered to obtain an open collector current sinking output operated on 9 to 35 Vdc. The output is a square wave pulse with a three-wire connection.

...disturbance insensitive and long-lived!
The turbine flow sensors of the product line Turbotron are sensors for flow rate measurement or dosing applications for liquids. Through its especially compact type, its very wide measuring range and its convincing precision of measurement, it has an almost unlimited application.
Function
The liquid flowing into the Turbotron is divided by the guiding blades in four split beams. These hit the rotor from four directions and put it in motion. The uniform loading of bearing from four sides causes the forces to cancel themselves out for the most part and wear is reduced to a minimum.
The extremely hard bearing materials, sapphire and hard metal, ensure in addition an extraordinary life expectancy.
The rotor rotation rate is now converted into an electrical pulse signal (frequency):
VTH and VTP are equipped with rotors which are fitted with magnets. A Hall effect sensor recognizes the rotation of the rotor.
VTI has stainless steel pins in the rotor. An inductive proximity switch detects the rotor rotation.
In both cases, a flow-proportional frequency signal (square wave signal) is available.

SIKA’s VTR turbine flow sensor allows you to determine precisely, dependably and easily the flow rates of different liquids, such as water and other low viscosity liquids, undert he most severe conditions. The VTR sensor is particularly robust and, due to the wide range of nominal diameters and five different pick-ups, can cope with even the most severe conditions.
How it works
The VTR sensor consists of the measuring turbine and a pick-up mounted on the outside. The liquid flows into the measuring turbine and causes the rotor to move. Due to the characteristic internal diameter the speed of rotation is directly proportional to the flow rate. The moving rotor blades are detected by the pick-up and this is converted into a pulsed signal proportional to the flow rate. The characteristic variable is the K-factor (pulses per litre) which is specific to each measuring unit, is determined by calibration and specified on the name plate. A five point calibration report can be supplied on request.
