Downpipe Check Valve

 N/A Downpipe Check Valve

6363: Downpipe Float Check Valve, 3/4" NPT Connections

6563-10: Downpipe Float Check Valve, 3/4" NPT Outlet, 3/8" Tube Inlet
  • Prevents siphoning or backflow of liquid through a downpipe installed in tank level gauging applications
  • Utilizes a specially designed float pin that rises up to seal the valve shut when liquid enters from the downpipe through the bottom of the unit
  • The advantage of a float check is that it doesn't create a pressure drop that would affect the level gauge reading (Spring-loaded check valves can impact the accuracy of a downpipe or bubbler system if installed at the tank entry point)
NOTE: Not recommended for use with heavy diesel fuel oil or other high viscosity liquids. Installation in conjunction with a gate valve will permit removal of check valve for inspection and cleaning. (We recommend cleaning the check valve once per year to ensure reliability.)

Features

Sanitary Configurations

 N/A These sensors are especially suited to a wide range of sanitary applications on storage or continuous processing vessels. The 316 stainless diaphragm is appropriate for flush mount, clean-in-place installation employing an FDA-approved silicone rubber O-ring seal to achieve the crevice-free, positive compression seal between diaphragm and tank liner. Sanitary tank mountings include flush weld mountings with product contact surfaces of 316L stainless. (Quick disconnect sanitary adapters are also available for sensor mounting.) You can choose from a number of KING-GAGE® display options to complement the ES2 for a complete tank level gauging system. These include digital indicators, HMI touch panels, and integrated networking solutions. Accurate tank gauging can be achieved using KING-GAGE® indicators that convert the proportional output into a volumetric measurement of tank level.

ES2 Signal Connection

 N/A The external connector of the ES2 transmitter affords an impermeable barrier against moisture infiltration of the transmitter housing. This connector receptacle has a metric M12 screw collar and is intended for plug type molded cable assemblies designed for 4-pole signal termination. Our ES2 transmitter package also includes a molded M12 cable (32 ft/10 m) to simplify installation and ensure a sealed connection at the unit - this molded cable meets IP68 standards for ingress protection.

Tank Level Display

 N/A Output from the ES2 transmitter can be monitored on KING-GAGE® indicators and multiple tank displays. Each of these display options also provide excitation power (24Vdc) to the transmitter through the signal loop cable.

KING-GAGE® indicators enable tank level to be represented as total volume, weight or depth of contents. Options include network connectivity including Ethernet.

Mounting

Mounting

 N/A Flush-mounting configurations are intended to meet the 3-A Sanitary Standards for clean-in-place applications. The ES2 transmitter fits directly into KING-GAGE® tank shells or with an adapter on other manufacturers' mounting shells.

Available Retrofit Adapters
  • Cherry-Burrell LevelMatic
  • Anderson Instrument
  • Rosemount/ Foxboro
  • Tank Mate
  • Wizard

Installation Options

 N/A The KING-GAGE® ES2 transmitter offers a choice of configurations to match your application needs. The integral stainless steel housing shown here includes a watertight connector for signal cable installation. Mounting lengths offered are intended to mate with tank fittings on non-insulated (single-wall) or insulated wall tanks. Adapters provide additional mounting options when retrofitting systems from other manufacturers.

Additional Information

Additional Information

 N/A ES2 Slimline Transmitter
  • Robust protection in wash-down environments
  • Continuous liquid level measurement
  • Two Wire Loop Powered (4–20 mA)
KING-GAGE® ES2 transmitters provide liquid level measurement for inventory monitoring. Add to their rugged reliability the major benefits of simplified service and maintenance. Performance characteristics of these transmitters include excellent stability and repeatability (better than 0.02% FS). Transmitter span accommodates a 3:1 turndown ratio (3:1 turndown ratio is applicable to 0–10 and 0–30 nominal range, refer to specifications for detailed span adjustment available on specific range models.) to match the application pressure range (i.e. tank depth) and the 4-20 mAdc output is compatible with PLCs or other control architecture using analog I/O.

KING-GAGE® ES2 transmitters are applicable to most tanks or process vessels whose contents remain at normal atmospheric pressure. They measure hydrostatic head pressure created by liquid depth in the tank and are unaffected by foaming or internal obstructions such as agitators. Unlike load cells, pressure based measurement has lower installation cost and is far simpler to maintain thus ensuring more reliable readings.

Transmitters used in sanitary processing must often endure cycles of rapid temperature fluctuation. Wash-down environments produce significant condensation on metallic surfaces that coupled with aggressive cleansing agents demand robust protection for these instruments. The ES2 transmitter's enhanced design uses encapsulation for full isolation of the internal electronics. This extends to the IP68 grade M12 signal connector that ensure integrity and long term reliability. You can be assured of a transmitter truly built for the demands and expectations of today's processing environment.

Performance and Reliability

Performance and Reliability

 N/A Unlike some other transmitters, ES2 has virtually no position sensitivity and its fast thermal recovery accommodates sanitary process environments. The ES2 transmitter's smaller diameter diaphragm face minimizes exposure to accidental impact and permits retrofit installation in many existing tank level fittings. Isolated meter terminals simplify accurate calibration of span and zero. Generous load capacity (up to 1300 ohms at 40 Vdc) can support extended cable runs or multiple loop receivers. We've provided ES2 transmitters with additional isolation from both moisture and corrosive potentials. The internal electronics are environmentally encapsulated, plus the external signal connection is hermetically sealed at the transmitter housing to reduce the opportunity for infiltration. These measures significantly add to the durability of our KING-GAGE® ES2 transmitter.
