LINE OF ELECTROMAGNETIC MEASURING FLOW CONVERTERS ИПРЭ-7 [ИПРЭ-7Т]

 
PURPOSE
A new more economic device for liquid flow rate measurement in which all the comments and suggestions made by our customers are realized distinguishes oneself from our previous models by higher accuracy, wider measurement range and provides measuring of the return flow of the medium measured. The liquid additional filtering is not required.
DELIVERY SET
ИПРЭ-7 [ИПРЭ-7Т] includes:
– initial flow transducer ППР-7
– measuring converter ИП-7 (ИП-7Т)
RANGE OF APPLICATION
Heating systems and thermal energy consumers, food industry factories. Commercial metering of liquid medium
flow rate, systems controlling liquid mediums as well as industrial waste water in pressure and free-flow pipe-lines. It can be used as meter-doser.
 
 
 
 
Recalibration interval                    3 years
Warranty period                   30 months
Lifetime                                       12 years min
 
The converter design provides a variant of separate installation of ППР-7 and ИП-7 (in use) with maximum tolerated communication line length from ИП to ППР being 100 m (variant 1) as well as integrated installation - mono-block installation of ППР-7 and ИП-7 (variant 2).
 
 
PRECISION CHARACTERISTICS:
 
The tolerated relative error limit when measuring the liquid volume and converting the flow rate into a frequency-pulse signal within the flow rate range is:
 
Version 1
± 1.0% within the range (Qmax ≥ Q ≥ Qmax/200);
 
 
Version 2
±1.0% within the range (Qmax ≥ Q ≥ Qmax/100);
±(0.01 Qmax/Qmeas)% within the range (Qmax/100 ≥ Q ≥ Qmax/200);
 
where
Qmax – the maximum flow rate value for the corresponding Ду, m3/h;
Qmeas – the measured flow rate value within the range Qmax/100 ≥ Q ≥ Qmax/200, m3/h.

 Straight sections of the pipe-line have diameter equal to the ППР internal diameter (Ду) (with deviation from the rated value ±2% max), and length not less than 5 internal diameters before ППР and not less than 3 internal diameters behind ППР.
 
Notes: 1. The ППР can be produced in waterproof modification for operation in wells.
2. As a lining material a thermoplastic material of a superstructural polymer category is used which having high resistance to chemical corrosive solvents, high hardness and rigidity, linear expansion coefficient 25–10-6 max (similar to that of metals), moisture absorption – 0.02% max. The above mentioned material properties together with the measuring channel glossy finish and the ideal position of electrodes guarantee obtaining of the ППР high operating characteristics.
