KROHNE► achieve more ► Enhanced repeatability in excess of API Chapter 4, for greater control on metering accuracy ► Quick change-out and no need to re-calibrate your prover ► One model fits all prover pipes from 3 - 36 inches ► Stainless steel wetted parts make the Micro-set suitable for most products

Micro-setProver Sphere DetectorNo matter how precisely you engineer your prover - and very few in the world can reach our quality - it's the sphere detection that determines the accuracy.Micro-set has all the features you need: ► Proven accuracy & reliability ► Repeatable for the lifetime of the detector ► Robust, durable and hard-wearing ► In service all around the world for over 25 years.

innovative Concept Micro-set Prover Sphere Detector Micro-set meter prover sphere detectors have shown themselves repeatable and reliable on NGL, butane, propane, rened petroleum products and crude oil. The detectors have performed well on hot, heavy, waxy crude oil and special ushing ports can be incorporated to enable cleaning during shut-down in extreme circumstances. Retrot model for replacing other types of detector KROHNE can manufacture special Micro-set sphere detectors to suit your application. Given detailed dimensional information regarding your existing sphere detector boss KROHNE...

advanced Performance Designed to perform beyond existing limitations Technical description The Micro-set meter prover sphere detector was originally designed and developed to satisfy a requirement for a 3” ball prover for butane and propane, a requirement which no existing proprietary unit could meet at the time. The Micro-set sphere detector is a mechanically activated position sensor for signalling the passage of a meter prover sphere. The unit is bolted to the prover loop pipe by means of a mounting boss, this allows the Micro-set plunger to protrude through the pipe wall and the prover sphere...

Proven to work betterCalibration tests Any Micro-set sphere detector that is set correctly using the same setting fixture can be exchanged in a pipe prover without significantly changing the base volume. Calibration tests undertaken by SGS, the international calibration specialists, on a four detector 10" prover loop produced the following results. The total spread of results from the four tests was only 0.0068%.

useful Options Proven options ensure reliable results under all circumstances The vast majority of detectors supplied are of standard design however there are two optional design enhancements that may be incorporated into both the ANSI 600 and ANSI 1500 models where application conditions are particularly onerous. In situ cleaning/ushing option Where the owing product is a crude oil with a high wax and/or sediment content there is the possibility that the build up of surface deposits within the detector body may prevent proper operation of the detector. Typically the movement of the plunger may...

better Performance Modernise your existing prover Retrots The Micro-set may be mounted on an existing prover which has been tted with mounting bosses for other detector types. To achieve this, the Micro-set may be supplied with an extended plunger and modied body to aid the direct replacement of the existing detector type. Alternatively the Micro-set can be tted with an extended plunger and an adaptor. Micro-set can be easily tted on site anywhere in th
