Tank Flange Mounting |
N/A The basic configuration is designed for mounting to any typical outlet near the bottom of the tank. It features a pipe flange connection (2", 3", or 4" class 150 ANSI). Since the TeleSensor sensing diaphragm responds to the pressure due to the head of liquid in the tank, the mounting location determines the starting level measurement point. Owing to the direct contact, all wetted materials should be selected based on compatibility with the tank’s contents. Standard diaphragms are titanium. Flange connectors are available in various materials as well. The rugged design of the TeleSensor tank unit is remarkably easy to maintain. |
Transmitter Signal Loop |
N/A As is typical of two wire transmitters, electrical power to the signal loop is supplied through twisted pair cable. Excitation voltage (+V) is provided by the receiving device or from a separate Vdc power supply installed in the loop. The actual voltage necessary for operation of the system will depend upon the overall load resistance of the loop. In most applications, the KING-GAGE® Digital Indicator or LevelBAR indicator provide 24 Vdc excitation to power the transmitter signal loop. |
Explosion Hazard Use (Zone One or Division One) |
N/A The TeleSensor requires no electrical energy for operation when using the 860 Sensor Control. It is possible to configure the tank level system without zener barriers or intrinsic safety provisions. The pneumatic signal may be routed to beyond the hazard zone (1,000 feet or more) to an indicator or transmitter. |
Pneumatic Operation |
N/A TeleSensor diaphragm unit is paired with a Sensor Control regulator to provide the continuous 1 CFH (cubic foot per hour) air flow to the underside of the diaphragm to attain pneumatic balance pressure. Constant back pressure regulation maintains linear 1:1 response throughout the entire operating range to ensure pneumatic pressure is directly equivalent to the hydrostatic head of liquid in the tank. |
Compressed Air Supply |
N/A Operation of the AcraSensor requires a compressed air/gas source providing supply pressure of 35-150 psig (2.4-10.3 bar). Pneumatic components require instrumentation-grade compressed air that is clean, dry and oil-free to ensure trouble free performance. |

Tank Gauging Applications |
N/A
Acting on the force balance principle, a pneumatic sensor generates air pressure equivalent to the hydrostatic force created by liquid depth. This pneumatic pressure is directed into the D/P transmitter. Pressure is converted to an electronic 4-20 mAdc output proportional to liquid depth. Twisted pair cabling is used to form the signal loop through which the remote indicator receives the transmitter output. The KING-GAGE® indicators shown in these system views correlate the transmitter output to total volume or weight of tank contents. This is determined by using a pressure versus capacity listing corresponding to the actual tank dimensions. The diaphragm unit is generally paired with the 868 D/P Sensor Control with integral transmitter. This converts the pneumatic isolation pressure to a proportional 4-20 mAdc signal suitable for process control or remote level indication. The standard TeleSensor + 868 D/P package combines accuracy, rugged durability, reduced maintenance, and long term stability for liquid level tank gauging. |

Rugged and Reliable Measurement |
N/A
These unique pneumatic sensors detect level by sensing hydrostatic pressure created by liquid depth. Acting on the force balance principle, a sensitive diaphragm is exposed to the liquid contents of the tank. Compressed air within the sensor creates a pneumatic pressure that balances the force of the liquid acting against the diaphragm. This compensating pneumatic pressure is directly proportional to the depth of liquid in the tank. The pneumatic force balance technique is virtually free from long term drift, hysteresis and temperature sensitivity unlike strain measurements (including load cells) since mechanical deflection of the diaphragm is not directly measured. The compensating pneumatic balance pressure which effectively isolates the sensor is converted to a proportional 4-20 mAdc signal or can be directly output to a suitable gauge. In actuality, the sensor is measuring the mass (weight) of fluid matter that can be correlated to units of standardized volume. |

Application Notes |
N/A Mounting flange and diaphragm are wetted surfaces requiring compatibility with process media. Location of the Sensor Control regulator should generally be no greater than 50 feet (15 m) from the TeleSensor unit. The sensor includes 15 feet (4.5 m) of bundled 3-tube cable for the pneumatic interconnections with the Sensor Control. Distances greater than 50 feet may increase response time of sensor to changes in liquid level in the tank. |
