Detect dangerous leaks in fiberglass tank's interstitial walls. Veeder-Root's Interstitial Sensor detects the presence of liquid between the double wall of fiberglass tanks. Liquid triggers an alarm signal to your TLS-450 Series, TLS4 Series, TLS-350 Series, and TLS-300 Series. You'll know immediately where the problem is so you can take swift action to prevent serious and costly safety and environmental problems.

Detect dangerous leaks in double-walled steel tanks. The presence of liquid in the interstitial space of double-walled tanks triggers an alarm in a TLS-450, TLS-350R, TLS-350, TLS-350J, ILS-350, TLS-300ior TLS-300C monitor. The visual and audible alarm tells you immediately where the problem is so you take quick and efficient action to help prevent safety and environmental issues. The TLS-450, TLS-350R, TLS-350, TLS-350J, ILS-350, TLS-300i or TLS-300C. TLS-250i and ILS-250 can also trigger an on-site alarm for even greater warning capability.

The Morrison "clock gauge" displays the liquid level reading of product stored in an aboveground tank. Measures the liquid level up to a maximum of 12 feet in height.

• Gauge face displays level reading in feet and inches. The hour hand (short hand) displays the number of feet and the minute hand (long hand) accurately displays the number of inches
• Easy to install and calibrate in a 2? tank top opening
• Accurate to 1/8 of an inch
• Easily read from 30 feet away
• Vapor tight construction
• Vapor tight fog free design
• Gauge rotates 360° making it easy for the face to be read from the desired orientation
• Visual indicators for high level (red) and low level (green) are applied to the dial face cover
• Standard float fits through a 2? schedule 40 pipe nipple
• Compatible with 2? Morrison model drop tube

Includes a 2-port RS-232 Module, a 3-Port Ethernet Module and a 2-Port USB Module

The Morrison "clock gauge" displays the liquid level of product stored in an aboveground storage tank. Measures the liquid level in tanks up to 12 feet high. The 918 audible alarm sounds when the liquid level in the tank reaches the user's specified level.

• Easy to install in a single 2? tank top opening, easy to calibrate
• Gauge face displays level reading in feet and inches. The hour hand (short hand) displays the number of feet and the minute hand (long hand) accurately displays the number of inches
• Gallon or liter reading gauge models available
• Accurate to ? of an inch
• Easily read from 30 feet away
• Vapor tight construction and fog free design
• Gauge rotates 360° making it easy for the face to be read from the desired orientation
• Visual indicators for high level (red) and low level (green)
• Floats fi t through a 2? schedule 40 pipe nipple
• Drop tube float compatible with Morrison 419 2? drop tube; reduces float entanglement when turbulent conditions are present

The 918AC System Interface is an AC-powered console designed to monitor 1 to 4 simple input switch devices and provide both audible and visual indication when an input switch is activated. In addition, the 918AC has the optional capability to add 1 to 4 configurable relay outputs to interface with remote audible and visual indicators or other external simple switch-activated devices.

• Audible alarm ON/OFF selectable by channel
• Auto silence ON/OFF selectable by channel
• Normally open (NO) or normally closed (NC) selectable on input and output
• Output relay activation selectable to one or more input channels
• Fail safe mode selectable to indicate power outage at console

Internal dispenser interface module, dispenser interface cable must be ordered separately
