Production Samplers

SA-77 Single Stroke Liquid Sampler

The SA-77 Sampler is a sample extraction tool for liquids production source (wellhead) testing. The samples that this unit extracts can then be transported to laboratory for analysis. Content ratios help aid in the determination of settings and production optimization.

The SA-77 Automatic Liquid Sampler operates by drawing samples from a pressurized liquid process and safely storing them in a receiver (glass1.5L or HDPE2.0L) bottle at atmospheric pressure. The control circuitry is pneumatically controlled. A full electrically controlled unit is also available.

Once the sample receiver (bottle) is full the SA-77 Liquid Sampler automatically stops cycling and cannot be restarted until the receiver is emptied. By functioning on a proportional to time base or proportional to flow base (with the use of a flow meter signal to control the pneumatic control input), operating personnel can obtain accurate sampling for lab analysis of either batch or continuous processes.

With all process wetted parts made of 316SST or Delrin® and seals available in a multitude of materials* the SA-77 is suitable for almost any liquid or liquid/gaseous process up to 350oF. The SA-77 Sampler can be configured to accept an intermittent pneumatic pulse or a constant supply allowing an adjustable sample rate from 1s/sec to 1s/120sec, with sample sizes variable from 1cc to 20cc/sample. This allows the filling of a sample receiver to be spread over a very short or a very wide time base. Safe operating pressure (SaOP) of the SA-77 sampler is 750psig for the standard unit and 1440psig for the HP version.

Service personnel and management will be amazed with the ease and economics of installation and maintenance as well as the low initial cost of the SA-77 Liquid Sampler.

    Applicable to a number of industries…
    The SA-77EHP Series of Liquid Sampler are electric samplers that can be used in all industries requiring flowing liquids to be sampled. Samples collected can then be transported to a laboratory for any analysis that is required by the applicable industry.

    -Tanker loading/unloading system
    -Truck off/on loading terminals
    -LACT units
    -Loss Control Auditing
    -Custody Transfer Points
    -Petrochemical Plants
    -Process Point Testing
    -Barge facilities

    Simple operation…
    The SA-77EHP Samplers operates by drawing samples from a pressurized liquid process and safely storing them in a receiver bottle at atmospheric pressure. The control circuitry is electrical and requires no pneumatics.

    A number of different configurations…
    You Control Version… Part Number: SA-77EHPUCONTROL, using your existing PLC, DCS or SCADA RTU we will supply a control narrative that makes your programming fast and simple.

    Complete self contained controls… be it flow triggered or time based we have designs that will meet your needs and electrical classifications.

    Corrosion resistant wetted materials…
    All wetted parts are made of 316SST, Kel-F® and seals available in a multitude of materials it is suitable for almost any liquid or liquid/gaseous process up to 160 o C (Standard unit to 93 oC). 300# and 600# ANSI class units available.
    Fast and adjustable cycle time periods… With a minimum cycle time period of 3 seconds, the sample control system can be configured to a wide range of applications…
    Adjustable sample size per cycle… The individual sample size can be varied from 2cc to 7cc/sample; this allows the filling of a sample receiver to be done over varied flow rates and/or time periods.

    SA-77 ELP Shutoff

    SA77-ELP is an economical method to provide safe and secure sampling shutoff at truck, ship or container unloading stations, custody transfer stations, or pipeline sampling stations. It provides a mechanical sample shutoff as well as an electrical signal to the sample control loop to indicate that the receiver bottle is full.
