New Design for Electric Motor for Crude Sampler

A new design of electric motor powered crude oil sampler has been delivered to the Middle East for installation on jetty sampling systems. The three-step action of the unit — isolate, grab, retract — is characteristic

of the original Maurer Instruments (UK) samplers that were developed in conjunction with BP Exploration in 1982.

The use of a bevel gearbox has allowed the motor to be co-axially mounted in line with the main sampling cell section, enabling a compact system that avoids many problems that occur with a cantilevered motor design. A feature of the Maurer design permits the unit to be split into easily serviced modules that can be removed from the flanged cell without having to break and open the pipeline.

The motor controller has a facility for spot-samples to be initiated remotely or at the site in addition to the separately controlled time or flow proportional sampling modes. The complete system is ATEX approved for use in hazardous areas. The motor controller which is housed in an approved ATEX approved enclosure is engineered for a 200/240 VAC single-phase supply.

Designed for installation in a full ANSI Class 300 sampling system, the sampling rate is variable to a maximum of 15 grabs per minute. A choice of sample volume — ½, 1, or 2 millilitres is available at purchase time.

Once again the Maurer engineering team has combined ingenuity with experience to produce an instrument that like its predecessors, the pneumatic and hydraulic samplers, are designed to give decades of continuous reliable operation.

Maurer Instruments Ltd has also recently obtained PED approval for their range of Constant Pressure Sample Receivers and Piston Internal Mixing Receivers (PIMR’s)

Maurer Instruments’ philosophy has always been to design and manufacturer its products up to a high standard than downwards to a cheap price. As a consequence, Maurer Turbine Flow Meters and Crude Oil Samplers are still continuing to operate reliably more than four decades after going into service.
