Quality Pap metering tank, Parshall tank experts, sewage tank,

Production and wholesale Pap groove / Parshall slot / flow tank / discharge groove / flowmeter private slot, we can produce a variety of national standard Pap groove / Parshall slot / flow tank / discharge groove / flowmeter private slot There are PVC / stainless steel / glass, steel and other materials Product use: Parshall flume and ultrasonic flowmeter WL-1A1 type with the use (see table below) the size of the inner channel flow turn into high and low level. Open channel flow measurement in the water. Applications flowmeter has urban water supply aqueducts, thermal power plant cooling water diversion and drainage, sewage treatment and discharge flow into sewers, industrial and mining wastewater discharge and water conservancy and agricultural irrigation channels.

Flow range: 10 liters / sec to 10 m3 / s (from the Parshall tank equipped with standard decision) the greater the flow, a corresponding increase in wall thickness. Note: 1, size and channel Parshall tank installation, please the user according to the site conditions. 2, the center line of Parshall slot coincides with the center line of the channel, so that water does not appear to enter Parshall slot bias. 3, Parshall flume water, water flow pattern to the free stream. Parshall slot submergence degree, is less than a predetermined threshold submergence degree. 4, the upper reaches of Parshall tank should have more than five times the width of the straight section channels, so that water can smoothly enter Parshall slot. That is not about bias, there is no channel formation gradient momentum. 5, Parshall tank installed on the channel you want to secure. And channel side walls, bottom drainage should be closely linked, not leaking. So that water flows through the metering of all parts of Parshall slot. Metering site Parshall slot is the slot throat section. In most cases, the measuring tank ultrasonic flowmeter selection Parshall tank, his installation consists of the following steps: 1, open channel construction installation preparation Before installing the first look at the terrain, the water inlet must be higher than the outlet, make sure water level difference, the water flow, which is the key to success Parshall slot open channel flow meter installation. Parshall measuring tank simulation Figure 2, Parshall Parshall slot into the open channel downstream of the discharge opening groove water level difference, discharge flow, water potential difference is not enough, should elevate Parshall tank, increasing the water level difference. To ensure that Pakistan break trough before the straight section 1 to 3 meters. 3, reinforced Parshall Parshall slot groove around with concreting, ensure all the water from the tank through the Parshall. To Parshall holding tank at about the level of reinforcement to prevent tilt, to prevent deformation. 4, 5 installation in several cases, special precautions must be guaranteed Parshall flume downstream water level difference, will not discharge water flow. This is the key issue to install. 6, after instrumentation wiring Parshall tank installed, to wait before the concrete sets were meter installation. Under normal circumstances it should be installed by meter technicians and debugging. Signal transmission cable separate body such as distance, the user can take longer. Distance is generally less than 2000 m, otherwise the connection test should be done in the field.
