Liquid Solids Control, Inc.
We provide continuous In-Line measurement of concentration, typically displayed as: %, % Solids, Brix, RI, or various engineering units.
We are known around the world for unique innovation without compromise, sophistication while maintaining user simplicity, and superb service to our extremely wide customer base. Serving all major Pulp and Paper industries.
PULP AND PAPER INDUSTRY
•Heavy black liquor solids
•Weak black liquor solids
•Red liquor solids
•Brown stock wash water
•Various acids; sulfuric, hydrochloric, nitric, etc.

Our refractometers measures dissolved solids (soluble solids) using the "critical angle" technique (an interface measurement of refractive index). This measurement technique is not sensitive to suspended solids, turbidity, entrained air, viscosity, color, transparency, opacity, or flow rate, and the output readings are automatically corrected for variations in process temperature. The electronic circuitry includes a signal output, adjustable in both frequency and duration, for automatic washing of the sapphire sensing window face, when/if required. The measurement is displayed in the most useful terms for that particular application. The most common read-out units are % Solids, Refractive Index and TTA.
Model 1022 = The Ultimate in Reliability
With keen focus on functional reliability - employing a truly dependable and accurate system of the highest quality - LSC again demonstrates its continual leadership and is stepping out front offering the Model 1022 Automatic Liquor Divert System. Contributing to LSC's extensive experience in the design and development of this equipment were many invaluable suggestions and mandates from several of the most prominent users/customers within the Pulp and Paper Industry. The LSC Model 1022 performs all necessary operational functions, including a number of "first ever" features, and fully complies with all recommendations of B.L.R.B.A.C.
With all hardware and software designed specifically for this application, the Model 1022 is an Automatic Liquor Divert System well ahead of its time, equally appropriate as a devoted standalone system (operates the Divert Valve directly) or integrated with a modern DCS or Burner Management System through various discrete dry contacts.
On-Line Measurement of Dissolved Solids
Model 326 Introduction
Liquid Solids Control is stepping out front, once again, with the Model 326 Refractometer. It offers a large 8.4" LED Touch- Screen Display, as well as, an Ethernet connection for remote access via a web browser (we recommend Firefox). Providing a direct link to all of the instrument’s information, the Model 326 gives the customer the flexibility and convenience of interfacing with the unit from any location within the plant’s network (instrument shop/maintenance shop, control room, etc.). Furthermore, when needed, your IT department can set-up a VPN allowing the LSC factory to troubleshoot your refractometer remotely, saving you time and money. For customers that do not have their instruments networked, we have incorporated a USB port which allows the technician to off-load all diagnostic files (history, event alarms and calibration files), so that they can be e-mailed to LSC for troubleshooting assistance.
Liquid Solids Control provides solutions for all installations. A variety of end fittings and flanges are readily available to complement the Model 326 process refractometer.
Flow Cells and End Fittings
Pulp & Paper Industry
The Model 326 Process Refractometer can be used to improve the entire efficiency of the “Kraft” liquor process, from the brown-stock washers, through the multiple-effect evaporators, concentrator, recovery boiler and even the dissolving tank.
The Liquid Solids Control Gate Adaptor provides the means for simple and quick removal of a sensing head from an active black liquor process pipeline, while ensuring the ultimate in safety. This dedicated unit eliminates the need for costly “By-Pass Loops”, which tend to be a bother by either leaking or plugging and even unscheduled process line shutdown to allow for maintenance.
The gate adaptor (duplex 2205) employs a completely captive slide plate, mechanically sure, operated by an eccentric cam. Operation of the Gate Adaptor is accomplished by turning a 1" (25 mm) hex operator just under 1/2 turn. Double Teflon seals are provided against both sides of the slide plate.
The Gate Adaptor provides for an external lock “fully open” or locked “fully closed” additionally providing positive and physical indication of “fully open” or “fully closed”.
The LSC Model 326 offers accurate in-line concentration measurements in the chemical, petrochemical and other various industrial process applications. Continuous monitoring enables uniform product quality and minimizes waste, as well as provides instant feedback on any process changes.
Linear and Non-Linear Applications
There are hundreds of ideal applications for process refractometers within the chemical and petrochemical industries. Some process measurements are linear, and some are not. The Model 326 has the ability to linearize/shape, or reverse, any customer’s product characteristics. This allows the process refractometer to track and produce accurate concentration measurements of products with a non-linear refractive index curve. Multiple linearized calibration tables may be stored and selected, as required. If desired, the measurement units, calibration, and correction points can selectively be changed at will, via the user-friendly touch-screen or remote web browser interface. The 4-20 mA output signal is automatically calibrated to the selected measurement range.
Intrinsically Safe Installations
Through the use of intrinsic safety barriers, the LSC Model 326 Sensing Head (either the in-line style or insertion probe) can easily be operated in a hazardous area, being intrinsically safe to the highest level. The sensing head is classified as a “Simple Apparatus”. Our system’s unique design allows for the sensing head to be located up to 500 feet (150 meters) away from the electronic enclosure. This exclusive feature eliminates various cumbersome problems associated with distance limitations that can occur when using other process instruments. The flexibility of the Model 326 allows the user to locate the electronics enclosure in the most convenient “safe zone”.
Dimensions & Weights
All flow cells that Liquid Solids Control manufacture are tailor-made to the requirements of the customer’s installation. This includes the line size, connection type and material. Typical length for single flanged pipe sections is 18" face to face. Dual pipe spools are 28".
