JC-MQLLJ series Flowmeter Is used to measure the enterprise gravity tube (drainage) flow meter track new sewage discharge measurement, referred to as 'water meter'. It is widely used to measure sewage petroleum, chemical, textile, pharmaceutical industry, urban pollution control and environmental protection departments monitoring one of the necessary instruments of sewage, agricultural irrigation water sector but also the necessary emission measurement instruments.
The meter uses hydraulic flow measurement, ultrasonic positioning, micro processing, digital display technology, in a relatively harsh environment installation, automatic measurement, high reliability and strong anti-dry capability. Easy installation and maintenance, Reading simple.

Product Principle:
JC-MQLLJ open channel flow meter is based on a specific shape Parshall measuring tank / weir plate metering slot guarantee a certain level of height, that a certain flow, the choice of Parshall flume / weir plate measuring tank as a specific flow channel, measuring high precision, easy installation, measure the liquid level sensor, instantaneous flow rate and total flow obtained values ​​89C52 MCU processing flow can be expressed as:
Q = KHn
Q: instantaneous flow (t / h) K: constant flow
H: liquid level n: n-th power value
Instantaneous flow totalizer handle obtained by the accumulated total flow.

Application area:
Because of flowmeter non-pressure flow characteristics, it is widely used in sewage outfall, used in chemical, metallurgy, environmental protection, pharmaceutical companies and other types of wastewater measurement and control.

Construction installation:
Before installing the first look at the terrain, the water inlet must be higher than the outlet, make sure that there is water poor, the water flow, which is the key to success Parshall slot open channel flow meter installation.

Parshall tank installation:

The first step: Parshall slot into the open channel

Requirements: (1) Parshall tank water level downstream of the discharge port is poor, discharge flow, water potential difference is not enough, should elevate Parshall tank, increasing the water level difference.
(2) to ensure that Pakistan break trough before the straight section 1 to 3 meters.

Step two: with concrete poured in Parshall tank around to ensure that water from Parshall slot after all.

Requirements: when Parshall tank installation level.

Parshall tank installed several situations:

Install the most critical point Parshall slot:
Parshall tank must ensure downstream water level difference, discharge flow, not water

Intelligent flow indicator:
Intelligent flow indicator is a new product developed by our factory, CPU is using AT89C52 microprocessor, the generic software support, you can simultaneously integrated flow and instantaneous flow display.
