Kenco Engineering liquid level gauges

Since its beginning in 1958, KENCO Engineering Company has been recognized as a key supplier of instrumentation for various industries, including oil and gas, petrochemical, power, pulp and paper, water, and waste treatment. KENCO enjoys worldwide recognition and leadership with its line of Liquid Level Gauges, which are used as visual measurement devices in various tank gauging applications. KENCO’s Oil Level Controllers are the standard device worldwide for measuring and controlling the amount of lube oil consumed in stationary engines and compressors. An outgrowth of our position of leadership in this market is the rest of our Gas Compression Components.

KENCO Engineering Company’s main facility is located in Tulsa, Oklahoma. KENCO also has a sales and warehousing facility in Baton Rouge, Louisiana, which serves its customer base in the state of Louisiana.

Liquid Level Gauges

K9900 Series Level Gauges

The patented K9900 Series Level Gauge features an innovative casting design that will simplify the installation process and eliminate other typical problems associated with gauge glass. The K9900 Series incorporates floating misalignment unions, which will allow the process connection centerlines to vary +/-1/4″. The gauge also has integral offset pattern valves with ball check shutoffs. 1/2″ FNPT vent and drain connections are inline for routine sight glass maintenance. The K9900 Series Level Gauge delivers safe, low maintenance, cost-effective solution to common sight glass applications.

8800 Series Level Gauges

The 8800 Series Level Gauge features 90° connections for ease of installation. The Gauge is fitted with inline 1/4″ FNPT vent and drain connections. Because the vent and drain connections are inline, glass cleaning is easy.

The center-line dimensional tolerance is 1/16″. This assures that the gauge will fit the mounting connection of the tank.

The sight tube of the 8800 Series Level Gauge is totally protected. Three sides of the gauge are enclosed with a metal frame, while the face of the gauge is protected with a polycarbonate shield. This shield can be custom calibrated to read tank volume or any other calibration. Refer to the Product Specifications tab to see the assortment of standard shield options.

Chemical Gauging Equipment

AccuRate® Pump

The KENCO AccuRate® Pump Setting Gauges utilize precision scientific glass to provide the most accurate reading possible for calibrating the flow rate of a chemical metering pump. They are also used to periodically monitor the performance and accuracy of a chemical injection system. Additionally, the AccuRate® gauge can be used as the primary containment reservoir of a fluid that will be pumped into a chemical injection system.

5700 Series Gauge

The 5700 Series Gauge provides a visual means for checking the contents of a bulk tank and a means for checking the injection rate of a chemical metering pump. The gauge is designed to operate in low to medium pressure applications up to 500 psi.

17000 Injection Rate Gauge

The 17000 Gauge functions as an injection rate gauge and also serves a bulk tank level gauge. The rating scale can be calibrated in a variety of options, such as GPM, GPH, GPD, LPM, LPH, or LPD. The maximum pump rate for a 12″ gauge section is 25 GPD. The sight tube in the 17000 is 1″ O.D. glass, which makes it ideal for viscous fluids. The top and bottom connections for this gauge are 1″ MNPT.

7000 Series Injection Rate Gauge

The 7000 Injection Rate Gauge is of the same construction as the 5700 gauge but is provided with a spring-loaded test valve similar to the valve supplied on the 779 Drum Gauge. The test valve is used to isolate the chemical supply tank from the gauge to conduct a one-minute calibration test for the chemical pump.


The 929 Series Pump Setting Gauge provides a means for checking the pumping rate of any chemical pump under actual pumping conditions in one minute. The gauge mounts in the pump’s suction line between the reservoir tank and the pump. It provides a visual gauge showing the liquid level in the reservoir in addition to a rapid means for setting the pump. The maximum pump rate for the 929 Series is 10 gallons per day, with each mark on the scale representing 1 quart per 24 hours. Models are available with a coupler plug so that the unit can be easily disconnected for calibrating several chemical pumps.

Sight Flow Indicators

KSF Cast Body Sight Flow Indicators

KSF cast body sight flow indicators have a heavy-duty cast construction to handle pressure and temperature requirements. A glass window on either side provides product visibility. Mechanical indicators to enhance the visibility of the media include flappers, rotors, and drip tubes. The cast body and threaded or flanged connections meet ANSI standards. Standard materials of construction are carbon steel, 316 SS, ductile iron, and bronze. Hastelloy C 276 and alloy 20 can also be supplied.

FVSF Full View Sight Flow Indicators

Full View Sight Flow Indicators are used to observe the flow of liquids in a piping system. 360° visibility provides convenient viewing from any angle. Designed for vertical applications. Threaded and flanged connections are available in a variety of sizes to match the diameter of the pipe being used. A wide range of endplate materials is available. Units can be made with any overall length if additional visibility is required.

ASF Armored Sight Flow Indicators

Armored Sight Flow Indicators are used to observe the flow of liquids in a piping system. A rigid steel housing surrounds the sight tube and provides additional strength and protection from mechanical impact. Threaded and flanged connections are available in a variety of sizes to match the diameter of the pipe being used. A wide range of housing materials is available. Units can be made with any overall length if additional visibility is required. Wetted materials consist of glass and connection endplates.

Sight Windows

Sight Windows are an effective and economical way of viewing tank, pressure vessel, piping system interiors. They are also referred to as sight glasses and are often replaceable or removable. Fluid clarity, color, level, and flow can be monitored through the window.

Sight Windows can be mounted by bolting, welding, or direct insertion into the end of the tank or pipe. Welding may require a radius pad that conforms to the pipe or curved vessels or a flat pad that mounts to a flat tank wall.
