MERITAPE LEVEL GAUGES
Metritape Operation Principle
Whether your application is an individual tank, a tank farm, a reservoir, or a river, our unique Metritape level sensor provides a reliable solution. This is because resistance-tape is remarkably different from other level sensors; in principle, appearance, and performance.
The reason for Metritape's success is its simple principle of operation and the high quality materials used in its construction. The sensor consists of a gold plated, stainless steel base strip, partially insulated from a gold plated wire that is wound around the base strip to form a helix. This helix is sheathed in various materials including Mylar, HastelloyTM, or TeflonTM, to insulate the sensor's inner elements from the liquid to be measured. Sliding the sheathed helix into a protective channel that leaves the front of the sensor exposed then completes the sensor. The sensor is generallly contained within a still pipe suspended from the top of the tank. However, other mounting options are available. Metritape Simply Works
With more than 25,000 Metritape sensors installed worldwide, this simple, rugged technology is selected because of its many features and benefits:
- No moving parts; nothing to wear out
- High reliability; virtually maintenance free
- Easy to install from tank-top; no need to empty tank
- Not adversely affected by agitation, foam, vapors, or product build up
- Calibration remains stable and drift free
- Intrinsically safe for use in flammable liquids
- Temperature detectors can be added to sensor
Metritape is the solution for a wide range of level gauging applications, including:
- Inventory Control
- Distributed Data Collection and Telemetry
- Process Tank Monitoring
- Hydrology and Flood Control
- Water and Wastewater
The Metritape level sensor is ideal for ponds, streams, tanks or sumps because of its high resolution; stable output and simple pipe mount installation. Since it has no moving parts and because specific gravity and viscosity do not adversely affect its output, Metritape is perfect for gauging raw sewage and sludge. Hundreds of municipalities and treatment plants use this reliable sensor in diverse applications including cooling ponds, digesters, groundwater, reservoirs, raw sewage, sludge pits, and wet wells.Slurries and Viscous Liquids
Metritape has proven durability in the gauging of slurries and dense liquids. The sensor's smooth, non-mechanical design resists buildup and is unaffected by agitation. Heavy ores, syrups, viscous muds and high viscosity oils do not hamper its operation. Applications include coal slurries, drilling mud, iron ore slurries, lime slurries and pulp and paper.Petroleum
The Metritape sensor's outer sheath gives it a smooth, nonstick surface ideal for gauging waxy crudes and heavy oils. Its chemically inert surface is also ideal for gauging refined products. Up to three temperature detectors can be built into the Level / Temp model which carries full intrinsic safety approvals. Applications include avgas, bunker C, crude, diesel oil, fuel oil, gasoline, jet fuel and naptha.Chemicals
Organics, inorganics, solvents, toxic substances and chemical waste tanks have all been successfully gauged with resistance-tape level sensors. Applications include acetic acid, acetone, benzene, caustics, chromate, condensate, methanol, phenol, plating solutions, sulfuric acid, toluene and xylene.Metritape Product Selection
The Metritape product line includes Aquatape for water and wastewater, Petrotape for petroleum and fuel, Chemtape for chemicals and petrochemicals and the LA sensor series for higher temperatures and pressures.

Aquatape is a water level gauge consisting of a Metritape sensor, available in lengths between three and 50 ft, a 4-20mA transmitter with built in transient protection and electrical noise filtering, a sensor filter and PVC housing. It offers output that is not hampered by agitation, vapor, sludge, foam, product build-up, internal tank structure or floating debris. This gauge contains no moving parts, making it suitable for gauging level in municipal water, wastewater, sewage and slurries. It is also suitable for tanks, wells, ponds, rivers, and lift stations.
The Petrotape gauging system is designed for monitoring above or below ground storage tanks. Gauged products include gasoline, fuel oils, crude oils, kerosene and diesel fuel with temperatures up to 225° F. This packaged system consists of a Hastelloy jacketed Metritape sensor, a compact filter assembly, a sensor housing and a two-wire 4-20mA current transmitter. It is available in lengths of 3 to 100 feet. The filter assembly protects the sensor from moisture and contaminates and provides pressure equalization. The stainless steel sensor housing mounts to a 3-inch flange.
The Chemtape gauging system is designed for monitoring above or below ground storage tanks. Gauged products include general industrial chemicals, pharmaceuticals, and petrochemicals with temperatures up to 225°F. The packaged system consists of the Metritape sensor, with either a Hastelloy C276 or an FEP Teflon jacket, compact filter assembly, a sensor housing and a two-wire 4-20mA current transmitter. It is available in overall lengths of 3 to 100 feet. The filter assembly protects the sensor from moisture and contaminates and provides pressure equalization.
LA Sensor Series
The LA series Metritape sensors are a modular approach to system building allowing selection of various sensors, sensor housings and instruments tailored to meet specific customer requirements. The LA Series consists of three models: LA, LA-HN(HP), and LA-AF. All LA sensors are available in lengths of up to 100 ft and all can have up to three RTD temperature detectors mounted within the sensor envelope at specified locations.
