The transmitter has a highly accurate silicon piezoresistive pressure sensor as a sensing element. It is capable of continuously sensing and measuring liquid level with high precision. Tek-Trol's Submersible Level Transmitters have several level ranges, output options, and custom cable lengths, ensuring a perfect fit for new or existing installations. They are frequently used with a SCADA, PLC, or compatible display/control system for liquid level indication or control. 2.2 Measuring Principle The Tek-Sub 4800B Submersible Level Transmitter consists of a sensor attached to a long cable, which is lowered to the bottom of a tank or well. The sensor operates by measuring the hydrostatic pressure of the liquid. Hydrostatic pressure (or head pressure) is the pressure exerted by the liquid in the tank or well. The hydrostatic pressure measured by the sensor is determined by two parameters: the density and height of the liquid. With liquid density remaining constant, changes in hydrostatic pressure necessarily reflect a difference in liquid level. Fig.1. Measuring Principle www.tek-trol.com 5 Instruction Manual Tek-Sub 4800B 2.3 Operation Typical Tek-Sub 4800B Submersible Level Transmitter application. TechnologySolutions Fig.2. Mounting the transmitter The pressure at the bottom of the tank is related to the height of the liquid. This pressure is called hydrostatic pressure or head pressure. Typical units for measurement of hydrostatic pressure are inches, feet, or meters of water column. In a water column, the hydrostatic pressure of 27.7" w.c. is approximately equivalent of 1 PSI. The volume of water or shape of the tank or vessel does not affect the hydrostatic head pressure as it is height of water that affects the pressure. Whether it is in a large water tank or a small bucket of water, the hydrostatic pressure of 27.7" w.c. is the same. Modern PLC's and HMI's can calculate the liquid level of a tank by entering the geometry of the tank and the specific gravity of the liquid. www.tek-trol.com 6 Instruction Manual Tek-Sub 4800B 2.4 Technical Specification TechnologySolutions Pressure range Pressure type Over pressure Accuracy Temperature coefficient-zero Temperature coefficient-span Long term stability 5 psig to 20 psig (3.5 mH2O to 14 mH2O), Other ranges available Gauge (Vented) 150% of Span ±0.5% FS ±0.75% FS (typ.), ±1.5% FS (max.)
