DC-1510

0% to 50%
ATEX Zone 1
rapid response

A water in oil transmitter designed for on-line monitoring of oil and other non-conductive liquids.

This device provides on-line water in oil monitoring of crude, fuel, hydraulic and lubricating oils for traces of water with equal accuracy, for alerting operators to the danger of water breakthrough, or as a quality control check on custody transfer applications.

The DC-1510 monitor operates on the capacitance principle: the higher the water cut the greater the capacitance. The microprocessor-based electronics incorporate sophisticated algorithms to compensate for temperature and dielectric variations, which facilitates high resolution and stable results.

Robust engineering, combined with a 4 to 20 mA output, makes this a reliable and easy to use instrument for water or base sediment and water (BS&W) for precise measurement of water volume between 0 % and 80 %.

The DC-1510 is suitable for by-pass or slip-stream type installations. This method can be installed on systems with small pipe diameters, offering ease of calibration and sampling. (See DC-3510 for direct insertion option.)

Installation of the DC-1510 water in oil monitor is simple. The device may be oriented in either a vertical or horizontal direction, with process flanges located on the same or opposing sides. This installation flexibility helps piping designers avoid placement of the instrument in a gas trap or water trap.

Adequate flow is required to ensure that 'free' water does not drop out within the monitor or sample system, and that the take off point provides a representative sample.

It is available with 1" or 2" flanged process connections ranging from 150 to 1500# ANSI pressure ratings. For non-flanged applications, we offer 3/4" or 1" NPT threaded ports.
