The Hawker Flexicap Continuous Level Indicating/Control System from HMA Instrumentation is suitable for water-based liquids, mineral and vegetable oils, hydrocarbons, acids, and process blends, etc. It is unaffected by pressure or vacuum, with a 4 to 20 mA output. It features four fully-adjustable set points, an easily readable contents indicator, up to 3 km separation between the control unit and transmitter, no moving parts, and a flexible design whereby the control unit interfaces with any two-wire loop powered transmitter.
The Hawker Flexilevel 2 from HMA INSTRUMENTATION is a fully digitised instrument, with all functions set by means of a user-friendly keypad. The controller and probes combine to provide a complete system with digital indication, four control or alarm points, a 4 to 20 mA retransmission, and total isolation with full diagnostics.
The 990 is a DIN-mounted controller with digital display and two push button calibration. Tank level can be spanned and zeroed in seconds. A simulator mode allows for simulation of the level change in a tank, as well as checking the function of other equipment connected to the transmission loop. The digital display is in percentage, and can be forward or reverse acting.
The Flexicap FCP/420 series probes from HMA Instrumentation are standalone loop-powered transmitters that provide a 4 to 20 mA output proportional to depth. Zero and span adjustments are made inside the termination head. These are ideal for use with PCs and PLCs. However, they can be used in conjunction with any Hawker product that accepts a 4 to 20 mA input signal.
