    596 Drum Gauge Mounts in the 3/4" outlet of a horizontal 55 gallon drum. The glass sight tube is protected by a cast aluminum frame which is calibrated in gallons and liters indicating liquid content of the drum.

    599 Drum Gauge Is supplied with a 3/4" ball valve which when closed provides a means for checking the pump rate of a chemical pump. The connection for the chemical pump suction port is 1/4" NPT and is located on the front of the mounting nipple.

    779 Drum Gauge Comes complete with a spring loaded test valve for checking injection rates of chemical pumps. This gauge also mounts in the 3/4" tank outlet and indicates tank volume in gallons and liters. The connection for the chemical pump suction line is 1/4" NPT and is located as shown in the photograph.

    779-KS Drum Gauge Is designed to accommodate the mounting of some diaphragm operated chemical pumps on its side mounted 1/4" NPT outlet. Use this gauge to check the operation of any chemical pump. It the check valve of the chemical pump is not functioning properly the fluid level in the sight tube of the drum gauge will pulsate between pump strokes when the valve of the gauge is closed.

    Operating Instructions To check the pumping rate of a chemical pump -- depress the valve handle (or close the ball valve) closing the gauge glass off from the drum. Hold the valve closed for one minute and observe the change in level on the scale cast inside the gauge frame. The scale on the left hand side of the gauge is calibrated in quarts per twenty-four hours and the right is calibrated in liters per twenty-four hours.

    The maximum pump rate for the drum gauge is 25 gallons per day.

    787 Drum Gauge Provides a visual gauge indicating the chemical content of the drum and is supplied with a 2" ell for refilling the drum. The gauge is secured to the malleable iron elbow with a stainless steel clamp.

    810 Drum Gauge Is supplied with a vented 2" malleable iron elbow for refilling the drum and a test valve for checking the pumping rate.

    779-PB Drum Gauge Has a heavy-duty Schedule 120PVC head with a push-pull test valve. The Drum Gauge frame is our standard cast aluminum. There is a brace to support the weight of the gauge that is connected to the top of the drum rim and it also stabilizes the gauge from lateral movement. It has a 1/4" female NPT outlet.

    Optional Vent Connection
    The Drum Gauges are vented to atmosphere. These gauges can be supplied with a 1/4" NPT connection to vent the gauge back into the tank. To specify gauges with this connection, add "V" to the product number, i.e. 779-V
