Model IF-05 water measuring weir gauge
1 Characteristics
The whole volume photoelectric switch rotary encoder is used as the sensor, and the digital output is all digital
The performance is stable, reliable, no temperature drift, time drift, strong electromagnetic interference. Even after power failure, the measurement data is still correct
High resolution, ISO/DIS international standard recommended digital head sensor
Configurable RS485/232 communication interface or 4-20mA current loop output interface, directly connected with communication machine and computer
High reliability, long life (non-contact photoelectric switch rotary encoder life up to 100 thousand hours)
2 applicable fields
IF-05 type digital weir head measuring sensor is the use of standard type flow measuring building Parshall flume and "V" type groove, other weir trough and its stable water level, flow to calculate the flow water level measurement instrument. Can be measured using the flow and supporting the construction of various types, measurement of dam seepage flow for water conservancy and environmental monitoring, real-time measurement, etc. the sewage metering hydrological survey flow.
The output data of water level sensor is directly transmitted to PC computer, and the water level, flow parameters are calculated, displayed and recorded by computer. On a shielded twisted pair line, 32 water level sensors with built-in RS485 output function can be connected at the same time, and the computer group measurement and computer processing can be realized.
This instrument has high sensitivity and resolution (level measurement resolution of 0.5mm or higher), and stable and reliable performance, no temperature drift, overcomes the shortcoming and insufficient input type water level sensor and ultrasonic flow meter poor reliability.
3 structure and working principle
IF-05 digital water level sensor consists of photoelectric switch, rotary encoder, measuring wheel, float, measuring cable, balance hammer, hydrostatic well, shield and so on. The encoder is the whole volume of ultra low torque switch photoelectric rotary encoder, encoding part of the encoder is stainless steel, code element is the imported high quality photoelectric switch, wheel suspension measuring cable, float and counterweight measured on a rotating shaft. The float, the cable and the balance hammer are all made of stainless steel and corrosion resistant plastics, which have good mechanical properties and environmental adaptability. The hydrostatic well of the sensor is a stainless steel fine log with a diameter of 100mm- 120mm. It is easy to install and can work in a polluted and corrosive waterway for a long time.
The rotary encoder is installed at the upper end of the static well, and the static well is installed in the flow measuring weir slot. When the water level changes in the weir tank, the float can be well measuring cable driven hydrostatic drive wheel measuring photoelectric switch and rotary encoder 9-15bit rotation, gray code encoding data output and the corresponding water level. The measuring range of water level sensor is 0-250mm, 0-500mm, 0-1000mm, 0-2000mm and so on. It can be used with each type of flume to realize the monitoring of different flow.
The water level sensor of the open channel flowmeter and the static water well can also be installed on the bank and connected with the measuring flume.
