Product Description

water flowing rivers pipes streams flow rate parshall flume open channel flow meter

Open channel portable flow meter/ Doppler flow meter/ Area velocity flow meter

The DOF6000 series DOF6000-P Portable Open Channel Ultrasonic Flow Meter consists of Flow calculator and the Ultraflow QSD 6537 Sensor.

The Ultraflow QSD 6537 Sensor DOF6000-P Portable Open Channel Ultrasonic Flow Meter is used to measure water velocity, depth, and conductivity of water flowing in rivers, streams, open channels and pipes. When used with a companion Lanry DOF6000 Calculator, flow rate and total flow can also be calculated.

The flow calculator can calculate the cross-sectional area of partially filled pipe, open channel stream or river, for stream or river, with up to 20 coordinate points describing the river’s shape of cross section. It is suitable for various applications.

Usages:

♦ Permanent and portable sewer monitoring programs
♦ Wastewater treatment plants
♦ Industrial process measurement
♦ Irrigation channels
♦ Effluent flow measurement
♦ Spill monitoring
♦ Combined Sewer Overflows
♦ Sanitary Sewer Overflows
♦ Event Duration Monitoring

Product Instruction:

Ultrasonic Open Channel Flowmeter is a high precision flow measurement instrument, which use Transit Time Ultrasound principle to measure the flow in a variety of Flumes, Weirs or Troughs.

Working Principle:

The sensor is a transceiver which emits high frequency sound, which hits the medium surface and returns back to the sensor receiver. The time of travel of the ultrasound is inversely proportional to the height of the flowing medium. This way the height of the flowing medium is calculated. And with the algorithms programmed the Height, Flowrate and Total Flow are calculated and displayed..

Portable open channel flow meter

LCD display Doppler flowmeter

Multi-function sensor (Velocity,Depth,Temperature and Conductivity Measurement )

The fixing accessories of open channel flowmeter

The Grade 316 stainless Steel Mounting bracket

Wireless remote transmission date display

Suitable for irregular/regular channels or not filled pipe as followed figures shown.

A typical installation is in a pipe or culvert with diameters between 150mm and 2000 mm. The Ultraflow QSD 6537 should be located near the downstream end of a straight and clean culvert, where non-turbulent flow conditions are maximised. The mounting should ensure the unit sits right on the bottom to avoid debris catching beneath it.

It is recommended that in open pipe situations that the instrument is situated 5 times the diameter from the opening or discharge. This will allow instrument to measure the best possible laminar flow. Keep the instrument away from pipe joints. Corrugated culverts are not suitable for Ultraflow QSD 6537 instruments.

The installation of open channel

When installing in riverbed, underwater or other channels, the installation bracket can be directly welded to the bottom of the channel, or can be fixed with cement or other base as needed, as shown in the above figure.
