Mounting Location of the Hydran 201Ti

5.2.2.1

Warnings

For meaningful readings and good response time, the most important factors are proper
location and installation of the H201Ti. This Section details the most important consider-
ations for the installation of the H201Ti.
1. Always mount the H201 sensor on a full-bore gate or ball valve where there is
sufficient convective oil flow.
2. The H201Ti is installed on a valve with a 1.5-in nominal diameter (NPT female
threads). If necessary, use a reducing bushing.
Note: To ensure sufficient oil flow past the sensor's membrane, the nominal diameter of the
valve should never be less than 25 mm (1 in). Furthermore, to ensure optimum
performance of the H201Ti, the diameter should not exceed 76 mm (3 in).
3. The total distance between the H201Ti and the mounting point of the valve must not
exceed six times the nominal diameter of the valve (230 mm [9 in] for a 38-mm
[1.5-in] valve). See Figure B-1 on page B-1.
4. The body of the valve must be grounded.
