1. Introduction of P670 pressure differential clock
The P670 pressure differential meter is designed with a structure that can protect bellows pipes against excessive pressure, and can be used for measuring the differential pressure of the filter, flow meter, etc. using holes or to measure the water level of the tank. The P671-P672-P673 series belongs to the Wise pressure watch series, with a stainless steel Bellows tube mounted on a force equaliser that allows direct reading of the actual differential pressure.
The product is distributed only in Wise Vietnam.

4. How to install and operate P670 pressure differential clock
For 3-way manifold valve
(1) Balance valve.
(2) Low pressure valve (LP Valve).
(3) High pressure valve (HP Valve).
- First when installing a Wise pressure gauge, it is necessary to close all valves.
- Once installed, first open the valve (1), then open the valve (3) check if the cursor is only to "0", if there is an error, adjust zero point adjustment..
- Before operating, make sure that all air escapes from the meter by opening the air outlet at the top of the meter. Residual air can cause pressure measurement errors.
- Then, open the valve (2) and then close the valve (1). Then make sure that the watch has indicated the correct part of the pressure difference.
5. Note when using the watch
When using the Wise P670 series (P671 - P672 series) we need to note some of the following:
- To prevent damage to the differential measuring unit, operate the meter along with the 3-way and 5-way manifold valve and check the input of the high-pressure- low pressure line before installation.
- The pressure difference unit must be installed in a higher position than the pressure diffuser during the measurement of the pressure when and low in the process of measuring the liquid pressure difference.
- With a system with corrosive liquid, you must choose a corrosion-resistant diaphragm or side diaphragm.
- In case you choose side diaphragm, the high side and low side are not installed at the same time.
- Zero point adjustment is adjusted by screwing inside the watch, at which point the user needs to remove the oil cover on top of the watch so that it can be adjusted.
- In case of operation in a high-temperature liquid, use a seal pot to keep the liquid from entering the meter at the permissible temperature.
