Differential pressure regulators model R880 made of stainless steel 316L, when coupled with Asameters model 1900-1901-1903 in s.s. 316L, can keep flow rate constant in presence of variable inlet pressure (mod. 1911-13-15) or outlet pressure (mod. 1912-14-16).
Chief performances are:
a) maintaining a constant flow-rate independent of inlet pressure fluctuations
b) maintaining a constant flow-rate independent of outlet pressure fluctuations.
To ensure accurate indication in gas measurament, upstream or downstream pressure must be constant. This is not necessary in liquid service.
- metering tube plexiglas protection (mod. 1901-3)
- flow alarm switch for minimum and maximum flow rate
Suitable flow-ranges are:
AIR min 5 nl/h max 2.100 nl/h @ T= 20° C and P= 1013 mbar a
WATER min 0,07 l/h max 70 l/h.
On request they can be made no standard flow-rates on specific medium of customer.
Nominal length of reading scale: mm 63 (Model 1900) – mm 90 (Model 1901) – mm 240 (Model 1903).
Asameter connections are rear ¼” gas-F or NPT-F; special executions on request.
Manufacturing materials are: stainless steel 316L.
