Kotron® Model 801 RF Capacitance Transmitter for Level/Flow/Volume D E S C R I P T I O N The Kotron Model 801 Transmitter is a new generation RF Capacitance multi-function transmitter that offers the user unparalleled power. The preamplifier circuit provides installation flexibility of a 2500 feet maximum remote distance. The Model 801 can interface with two separate vessels, essentially making it a mini-multiplexer, while software mathematics allow for the sum or differential of the two signals. F E A T U R E S • Capability for dual input of two probes from separate vessels. • The level signal from one vessel can be mathematically added to or subtracted from another vessel. • Level/Volume and Level/Flow characterization for all standard vessels and flumes/weirs. • Integral keypad on front panel maintains NEMA 4X rating; no need to open the enclosure during calibration or setup. • Provides one 4–20 mA isolated analog output signal. • Four 10-amp SPDT relays provide complete flexibility from simple alarm applications to complex pump control including lead/lag alternation of pumps. • 16-character alphanumeric display of all parameters. • Display may be configured in units of level, volume, or flow. • Continuous diagnostics check all major functions of the device including integrity of the probe. A P P L I C A T I O N S • Hydrocarbons and solvents • Slurries • Viscous fluids • Unit may be remote mounted up to 2500 feet (760 m) using twisted, shielded pair cable. • Intrinsically safe version can be remote mounted to 800 feet (240 m) and is supplied with on-board barriers. • RS-232 for downloading of collected flow data (up to the last 31 days). • Open channel flow • High temperature/pressure liquids • Acids T E C H N O L O G Y The amount of capacitance developed in any vessel is determined by the size (surface area) of the probe, the distance from the probe to its ground reference, and the dielectric constant of the medium being measured. Considering that the probe’s mounting position is fixed and the dielectric of the medium is constant, then the amount of capacitance developed in a vessel becomes dependent upon the amount of the probe which is covered with media. T Y P I C A L As the media rises and falls in the tank, the amount of capacitance developed between the probe and the ground reference also rises and falls. The Pulsatel circuit mounted on the probe changes the capacitance signal to a digital waveform proportional to the change in level. The amplifier then converts this digital signal into an isolated 4–20 mA analog output signal. A P P L I C A T I O N S Level/Volume monitoring of two tanks The Model 801, with its dual input capability, can monitor the level or volume of two different tanks. The tanks can be of different sizes and configuration and contain different materials. The display will provide a visual indication of the level or volume and the alarms can be set up to provide high and low level detection on each tank. 2 P1 P2 HL HL LL LL T Y P I C A L A P P L I C A T I O N S Sum the volume of two tanks P1 Using the dual input, the 801 can measure the total volume of two tanks. For instance there may be a main storage tank plus a smaller day tank. The 801 will display the volume of each tank plus provide a 4–20 mA signal of the total volume. Each tank can be a different size and shape. Alarms can also be provided for high or low level detection. P2 Level differential The 801 is ideal for bar screen applications. Probes can be installed on either side of the bar screen. The 801 can measure the difference in level measured by the two probes. This will provide an indication that the bar screen requires cleaning. The 4–20 mA output can be provided on the actual level or on the level differential between the two probes. Alarms can also be set if the differential reaches a specific value.
