PU 2001 is a micro processor based flow and level monitor. It measures the level and the flow in either open channels, weirs or flums. A fibre optic connection give the possibility of greater distances between the sensor and the monitor wuthout the risk of signal interfernce. Alternatively a transmitter with a 4-20 mA signal output can be connected.

The measuring principle is to measure the level of liquid in the measuring channel or flume with the ultrasonic sensor alternatively pressure transmitter. As flow monitor, the measured level difference will be
calculated in the monitor. The flow in the flume is shown in the display at the same time as a mA-signal proportional to flow is generated from the monitor. As level monitor the level is presented at the same
time as a porportional mA-signal is generated in the same way. In the display both digital and analogue format can be shown. There are approximately 10 programmed flumes for flow measuring.

PU 2003 ultrasonic transmitter is for contact free measurement of liquid level in tanks, pools,
and similar applications. The monitor is one compact unit with a four digit display on the top used for calibration and indication of the measured levels.

The measuring principal is a crystal which generates an ultrasonic pulse which is carried through air towards the liquid surface where it is reflected and received by the monitor which then calculates yhe distance to the surface. The distance is shown on the display and output signal is an analogue signal 4-2MA.
A unique manipulation of the alarm makes it possible to program certain alarm functions and to receive an alarm at the mA signal. Error messages can be programmed at 2 or 22 mA output signal.
