Series TDC Remote Flow Controller coupled with a thermal dispersion flow switch (Series TDS) provides a complete system for leak detection, signaling high or low flow conditions, low flow cutoff, and pump or valve actuation. Controller features adjustable time delay for dampening of relay chatter, selectable NO or NC operation, and LED indication of sensor, relay, and power status. Model TDC1 accepts single switch input and single relay output. Model TDC2 accepts three switch inputs and two relay outputs.

The Series APM has a unique, rugged, NEMA 4X front panel design that makes it nearly impenetrable in typical applications. The weatherproof, UV resistant, large, dual line display allows for more information making it easier to read and even simpler to program. The intensity of the display can be adjusted allowing this meter to be utilized in dark rooms as well as outdoors, due to its sunlight readable display. It features up to eight visual alarm set points to trigger certain events and three function keys which can be programmed to provide direct menu access. With up to four relays available, the APM features latching, nonlatching, sampling, pump alteration control, and a fail-safe action. Offering programmable delay time, this meter prevents recognition of false maximum or minimum reading which may be caused by the start-up or unusual process events. The APM provides three security passwords that restrict modification of programmed settings. This unit has the ability to obtain non-linear input signals and linearize them with simple to use math functions such as square-root extractor, weirs and flumes exponential linearizer, horizontal round tank linearizer or general purpose 32-point linearizer. Unit accepts 0 to 20 mA, 4 to 20 mA, 0 to 5V, or ±10V inputs and requires 85-265 VAC or 12/24 VDC power supply. Choose from RS-232, RS-422/485 serial communication options or any available expansion modules, accessories, and enclosures.The APM is a 1/8 DIN digital panel meter specifically designed for displaying flow rate and total from a flow meter with an analog output such as 4 to 20 mA or 0 to 10V. The APM is particularly well-suited for flow applications and can be programmed for a wide variety of display configurations. The upper line can display either flow rate, total or grand total, and the lower line can display either flow rate, total, grand total, or engineering units. It is possible to display flow rate and total at the same time, a very unique feature on a 1/8 DIN digital panel meters.Note: Shallow depth meters will not work with this Series.
