mm ApplicationThis model of water meter is used to record the total
amount of cold water flowing through the pipeline. It cannot be
used to measure sewage and corrosive
liquids.Feature1. Using
non-contact sensors, does not affect the original performance of
mechanical water meters.2.
Using infrared radiation to enhance the anti-interference ability;
non-mechanical contact mode, will not cause garbled reading due to
mechanical looseness.3. Special
coding method, there is no dead zone of reading, the mechanical
rotation can keep the mechanical reading consistent with the
electronic reading when the word wheel is rotated to any
position.4. Low power design,
only power is required for
reading.5. Can be combined with
the meter reading system to establish a remote automatic meter
reading management system to truly realize meter reading
automation.6. The electronic
device complies with the standard of Electronic Remote Water Meter
(CJ/T224-2012)7. The agreement
is in line with the "Technical Conditions for Data Transmission of
Household Meters" CJ/T188-2004 or MODBUS or both parties.Conditions
of Use1. Water temperature: 0~
30°C Pressure: no more than 1MPa Working environment: Class
B2. Upstream flow field
sensitivity level: U10 Downstream flow field sensitivity level:
D53. Transmission mode is
divided into RS-485, MBUS bus transmission
mode.4. Communication
transmission rate: 2400bps or customized according to customer
requirements; Maximum distance for communication transmission:
1000mThe main technical parameters Indication error
limit1. The maximum allowable
error from the minimum flow (Q1) to the low zone that does not
include the boundary flow (Q2) is
±5%2. The maximum allowable
error from the high boundary including the boundary flow (Q2) to
the overload flow (Q4) is ±2%Dimensions and weightRemovable
screw-wing water meter Installation and
use1. Determine the diameter of
the water meter. Firstly, understand the flow rate in the pipeline.
It is better to use the flow rate close to the common flow. It is
not possible to determine the diameter of the water meter simply by
the diameter of the pipeline.2.
The upstream and downstream of the water meter should be installed
with the necessary straight pipe section or the equivalent of the
water flow rectifier. The length of the upstream straight pipe
section is not less than 10D, and the downstream straight pipe
section is not less than 5D (D is the nominal diameter of the water
meter). The rotation of the water flow caused by the elbow or the
centrifugal pump, it is necessary to install the rectifier in front
of the straight pipe section.3.
Newly installed pipelines should be cleaned of stones, muddy water
and other debris in the pipeline and installed with water meters to
prevent damage or malfunction of the water
meters.4. Install a filter with
the same nominal diameter of the water meter in the upstream of the
water meter. The filter should be taken out and cleaned frequently.
The debris accumulated in the filter should be cleaned to ensure
accurate metering.5. The water
meter should be installed coaxially with the upper and lower
straight pipe sections, and the gasket should not protrude into the
pipe to avoid the measurement
uncertainty.6. Installation
location should avoid exposure, freezing, pollution and flooding,
in order to disassemble and read the
meter.7. The water meter
installation should be bypassed to ensure that the water meter is
not stopped when the water meter is installed. Water meter
installation should pay attention to the water flow and the
direction of the arrow on the water case to prevent the reverse
installation, the valve should be installed upstream and downstream
of the water meter, and all open when
used.8. Prevent the steam from
entering the pipeline directly when installing the hot water
meter. /* March 10, 2023 17:59:20 */!function(){function
