to use.
7.4.3 Inlet and outlet temperature zero point, temperature calibration
The three-wire bridge connection mode of the electromagnetic heat meter Pt1000 thermal resistance
and Pt100 thermal resistance, the specific calibration method is detailed in the appendix.
7.4.4 Thermal resistance type
The electromagnetic heat meter has the selection function of pt1000 thermal resistance and pt100
thermal resistance. If the user wants to use Pt1000 thermal resistance in the temperature measurement
part, select pt1000; if the user wants to use pt100 thermal resistance in the temperature measurement
part, select pt100.
7.5 Total amount setting parameters
7.5.1 High and low flow total volume
The total high and low settings can change the cumulative total value of the flow, which is mainly used
for instrument maintenance and instrument replacement. The flow cumulative amount can be modified,
generally cannot exceed the maximum value counted by the counter (99999999999
）
.
7.5.2 Heat and cooling flow total volume
The setting method is the same as the high and low positions of the total flow. Set cumulative maximum
display 99999999999.
8 Installation requirements
In order to ensure the heat accuracy, usually a single-flow sensor for measuring cold and heat should be
installed at the water inlet, as shown in Figure 1.The flow direction of the fluid is the same as the arrow on the
energy meter.
Figure 1
The
energy meter
must work under the condition of full pipe, and the flowmeter cannot work normally when
the pipe is not full or empty.
The correct installation method of the
energy meter
should ensure that the pipe is filled with liquid and should
not be installed high on the pipe, as shown in Figure 2.
