Advantages

SATAM meters are Positive Displacement type meters. Their great efficiency has earned them a world-wide reputation :

Special design featuring a meter manifold in line and a seperate measuring chamber. This protects the measuring chamber from any eventual stress and strain from the installation piping.

High accuracy over a wide range of flow rates, superior by 1 to 10 to Weights and Measures requirements.

Very low repeatability error, less than 0.04%

Low head loss : 0.5 bar maxi (0.3 bar for the ZC17-24 and 48 models)

Exceptional accuracy over time, the accuracy curve of the meters hardly varying over a long period of use.

Service and maintenance simplified by the use of many identical and interchangeable parts.

Simplicity of design, the only moving parts being the 2 sets of blades and the rotor. This keeps maintenance costs to a minimum.

A wide range of accessories can be used to build metering units specially adapted to customer requirements.

Measuring Chamber

Thanks to its advanced technical design, SATAM is able to cover the entire range of flow rates, from 20 l/mn ( 5 USGPM) to 4200 l/mn (1100 USGPM), by the simple addition of measuring chambers.

Operating Principle

The product enters the measuring chamber at (A) following the direction of the arrows. The rotor and blades assembly (1-2) is set in motion by the pressure of the liquid on blades.

A certain amount of liquid (3) is held between two blades, measured and then directed towards to discharge manifold (B). The volume of liquid measured at easch rotation is therefore equal to 4 times the measured quantity (3).

Accuracy is provided by the extremely small clearance between the different elements of the meter.

The smooth curves of the meter pieces provide a steady, non-fluctuating flow, resulting in low head loss.

In mechanical version, an extended rotor shaft transmits its movement to the meter head using a calibrating device. The mechanism of the meter adjustment is stepless.

Mechanical Calibrating Mechanism

All the meters in the SATAM range are equipped with a Continuous adjustment calibrating mechanism. All meters are tested in the factory before delivery to the customer. This very accurate mechanism is based on the principle of differentials. By means of a calibration screw we can adjust as follows:

on ZC.17.12 Meters:
1 notch = 0.025% (adjustment range: 4% maximum)

on ZC.17.24/24 and ZC.17.24/48 Meters:
1 notch = 0.025% (adjustment range: 4% maximum)

on ZC.17.80/80, ZC.17.80/150 and ZC.17.80/250 Meters:
1 round = 0.1% (adjustment range 1.2% maximum)
