Controls and Instruments The Meriam Instrument Company 10984 Madison Avenue, Cleveland 2, Ohio Representatives in Principal Cities MANOMETERS, METERS AND CAUGES FOR ACCURATELY MEASURING PRESSURES, VACUUMS AND FLOWS OF LIQUIDS AND GASES e In. Mercury Pressure Gauge U-TYPE MANOMETERS For measuring pressure, vacuum or differential from only a few ounces to many pounds. In the Clean Out design (patented) the Pyrex U-tube and housing can be discon nected from the head and cleaned without disconnecting the piping. Available in 8 sizes from 6 in. to 50 in. for pressures up to 100 lb per sq in. Gland Packed type available for 250 lb per sq in. Write for Bulletin 1. FLOW METERS The H-Type Flow Meter-- Illustrated at the left is a direct reading well type manometer for measuring the flows of liquids, gases and steam across calibrated plates inserted in the line. The single straight Pyrex glass tube is gland packed top and bottom. Over flow well prevents indicating fluid . from being blown into the line if the differential pres sure should exceed the meter's range. Plain or flush type mounting for line pressures up to 250 lb per sq in. Send for Bulletin 18. MERCURY PRESSURE GAUGES For measuring low range air and gas pressures. Gauges are direct reading and so designed that the mercury can not be lost from the gauge either through spilling or overpressuring. Available in 3 and 6 in. sizes to measure 22 oz and 48 oz respectively. Unit scale gradu ations are in ounces. Each gauge is furnished complete with pet cock and necessary mercury. Write for Bulletin No. 3. WELL TYPE MANOMETERS For measuring pressure and vacuum, and differential directly from the scale, using water, red oil or mercury, without adding distances above and, below reference zero. Model A-203-- Furnished in wall, table and flush front mounting styles. Ranges 30 in. to 100 in. for pressures up to 250 lb per sq in. Model A-275-- Furnished in wall mounting and flush front styles only. Ranges from 6 in. to 24 in. for pres sures up to 150 lb per sq in Send for Bulletin B. DRAFT GAUGES Single Tube Draft Gauge Model GP Draft Gauges take accurate readings of low pressures, vacuums and differentials in\fractional inches of water. Furnished in single tube, also in 2-tube and 3-tube models for taking multiple readings on the same gauge. Send for Bulletin No. 4- Putsafion Absorber GAUGE PULSATION ABSORBERS The Gauge Pulsation Ab sorber provides a simple, effec tive method of preventing "hammer" and pulsing flow in a line from affecting the ac curacy of gauge readings, and protects the gauge from damage.
